Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, and in particular relates to a double-width double-station cutting machine. Background Art

[0002] Semi-cured sheets, also known as "PP sheets", are mainly composed of resin and reinforcing materials. They are indispensable insulating materials in PCB boards and are placed between layers of multi-layer circuit boards to play a role in circuit isolation. When manufacturers produce PP sheets, they are mostly produced and sold in roll form (the size of the roll material is mostly 1260mm*second slitting module (300)m, and the thickness ranges from 0.03mm to 0.2mm). When producing PCB boards, the PP sheets of the roll material are cut into rectangular materials of different sizes using a cutting device according to the layout requirements and production requirements of the PCB boards.

[0003] When using a cutting device to cut a PP sheet, the rolled PP sheet is first cut into strips in the length direction (at this time, the width of the strips matches the width of the PCB board), and then the strips are cut into rectangles in the width direction (at this time, the length of the rectangles matches the length of the PCB board). However, most existing cutting devices can only cut strips of one width. Rectangular materials with different width requirements require multiple processing, which is not conducive to further improving the cutting efficiency of rectangular materials.

[0062] The second slitting module 300 is assembled at the other end of the frame 100.

The plurality of second heating assemblies 320 are all assembled inside the frame 100. The plurality of second cutting blade assemblies 310 and the plurality of second heating assemblies 320 correspond one to one. The plurality of nip rollers 121 are respectively adapted to the first cutting blade assembly 230 and the second cutting blade assembly 310.

[0063] Among them, after the push plate assembly 220 is in operation, it can adjust the positions of multiple first cutter assemblies 230 respectively, and cut the raw materials into multiple strips in the length direction through multiple first cutter assemblies 230, and multiple second heating assemblies 320 can cut the multiple strips in the width direction respectively.

[0064] Furthermore, a control module is provided on one side of the rack 100, and an automatic deviation correction module and a meter counter are also provided inside the rack 100. The automatic deviation correction module and the meter counter are both existing mature technologies and will not be further described here. In this embodiment, the meter counter can accurately calculate the usable length of the roll material, and the automatic deviation correction module can monitor the offset state and offset amount of the roll material, and correct the roll material in time to improve the cutting accuracy of strip materials and rectangular materials.

[0065] Here, an air supply module is used in conjunction with the device, and the air supply module can provide driving force for the pneumatic components inside the device.

[0066] It should be noted that, in this embodiment, the length direction refers to the flow direction of the raw material, the width direction refers to the direction perpendicular to the length direction in the horizontal plane, and the morphology of the prepreg in each stage during the processing is changed in the following order from front to back: roll material, strip material, and rectangular material.

[0067] Specifically, both sides of the multiple pressing rollers 121 are equipped with driving elements, and the driving elements can drive the pressing rollers 121 to move. In this embodiment, the pressing roller 121 adapted to the first cutter assembly 230 is fitted with the first cutter assembly 230 under the action of the driving element. Through the cooperation of the first cutter assembly 230 and the above-mentioned pressing roller 121, the rolled material can be cut. The pressing roller 121 adapted to the second cutter assembly 310 is fitted with the guide roller 120 closest to it under the action of the driving element. It can tension the strip material to avoid distortion of the strip material when the second cutter assembly 310 cuts the strip material.

[0068] In this embodiment, the roll material is assembled on the outside of the loading module 110, and the raw material is pulled into the rack 100. The push plate assembly 220 is started. According to the width requirement of the PCB board, the positions of the multiple first cutter assemblies 230 are adjusted respectively by the push plate assembly 220. The first heating assembly 240 is started, so that the first heating assembly 240 is close to the roll material and heats the position of the roll material close to the first cutter assembly 230. The first cutter assembly 230 is started and the roll material pulled into the rack 100 is cut in the length direction by the first cutter assembly 230. The roll material is cut into strips of multiple widths. The electrical module is started. The electrical module drives the multiple guide rollers 120 to rotate, and the multiple guide rollers 120 cooperate to pull the multiple strip materials respectively, so that the multiple strip materials pass through the interior of the multiple second cutter assemblies 310 respectively, and the second heating assemblies 320 are started. The multiple strip materials are heated by the multiple second heating assemblies 320 respectively, and the second cutter assemblies 310 are started so that the multiple second cutter assemblies 310 operate independently. The multiple strip materials are cut by the multiple second cutter assemblies 310 to obtain rectangular materials of different sizes, so that the device can cut rectangular materials of different sizes at the same time according to the various size requirements during PCB board production, thereby improving cutting efficiency.

[0069] See also Figures 6 and 7 As shown, the push plate assembly 220 includes multiple first drive motors 221, transmission belts 222, mounting brackets 223, first cylinders 224, tool holder push plates 225 and drag chains 226. Multiple first drive motors 221 are respectively assembled on both sides of the first tool holder assembly 210, and the output ends of the multiple first drive motors 221 are connected through transmission belts 222. The mounting bracket 223 is slidably connected to the first tool holder assembly 210, and the mounting bracket 223 and the transmission belt 222 are fixedly connected.

[0070] Specifically, the mounting frame 223 is equipped with a clamping plate assembly and multiple first sliders, the clamping plate assembly is fixedly connected to the transmission belt 222, the mounting frame 223 and the transmission belt 222 are fixedly connected through the clamping plate assembly, the internal sliding connection of the multiple first sliders is connected to the first slide rail, the first slide rail and the first tool holder assembly 210 are fixedly connected, and the mounting frame 223 and the first tool holder assembly 210 are slidably connected through the cooperation of the first slider and the first slide rail.

[0071] In this embodiment, when it is necessary to cut strip materials of different widths, the first drive motor 221 is started, so that the output end of the first drive motor 221 rotates, and the transmission belt 222 is driven to operate by the first drive motor 221. The transmission belt 222 is fixedly connected to the mounting frame 223, so that the transmission belt 222 drives the mounting frame 223 to move. Since the first cylinder 224 is fixed on the mounting frame 223 and the knife seat push plate 225 is fixed to the output end of the first cylinder 224, the first cylinder 224 and the knife seat push plate 225 will move synchronously with the mounting frame 223. When the mounting frame 223 approaches any first cutter assembly 230 that needs to be adjusted, the first cylinder 224 is started, so that the output end of the first cylinder 224 is pushed out, and the first cylinder 224 is fixedly connected to the knife seat push plate 225, so that the first cylinder 224 drives The knife seat push plate 225 moves. When the knife seat push plate 225 and the first cutter assembly 230 are in contact with each other, the first drive motor 221 is started again, so that the first drive motor 221 drives the knife seat push plate 225 to move, and pushes the first cutter assembly 230 to move through the knife seat push plate 225, so that the first cutter assembly 230 moves to the specified position. After the adjustment is completed, the first cylinder 224 is started in the reverse direction, so that the output end of the first cylinder 224 contracts, and the knife seat push plate 225 is driven to move, so that the knife seat push plate 225 is away from the first cutter assembly 230, thereby completing the adjustment of the position of the first cutter assembly 230. Similarly, the positions of other first cutter assemblies 230 are adjusted, so that multiple first cutter assemblies 230 can cut the roll material according to the width size requirements, so that the roll material can be cut into strip materials of different width sizes.

[0072] See also Figures 8 and 9As shown, a guide rail assembly 211 is fixed to the upper end of the first tool holder assembly 210, and the first cutter assembly 230 includes a first guide block 231, a tool holder base plate 232, a push plate base 233, a base 234, a shell 235, a telescopic rod 236, a circular knife 237 and a positioning block 238.

The circular knife 237 is slidably connected to the inside of the shell 235, and the circular knife 237 is rotatably connected to the end of the telescopic rod 236 away from the pneumatic chamber 239. The positioning block 238 is fixed to the upper end of the base 234.

[0073] Specifically, after the tool holder push plate 225 and the push plate base 233 are fitted together, when the first driving motor 221 drives the tool holder push plate 225 to move, it can also drive the push plate base 233 to move at the same time.

[0074] Furthermore, an air inlet is provided at one end of the pneumatic cavity 239, and the air inlet and the air supply module are connected through a pipeline.

[0075] In this embodiment, when the position of the first cutter assembly 230 needs to be adjusted according to the width size requirement, the first drive motor 221 is started, and the knife seat push plate 225 is driven to move by the first drive motor 221, and the push plate base 233 is pushed by the knife seat push plate 225. The push plate base 233 is fixedly connected to the knife holder base plate 232, so that the push plate base 233 drives the knife holder base plate 232 to move, and at the same time drives the telescopic rod 236 to move. When the telescopic rod 236 moves to the target position, the air supply module is started, and the push plate 233 is fixedly connected to the knife holder base plate 232. The air supply module injects gas into the pneumatic cavity 239, thereby pushing the telescopic rod 236 to move, and the telescopic rod 236 drives the circular knife 237 to move, so that the circular knife 237 moves toward the direction close to the rolled material. At the same time, the driving element is started, so that the pressure roller 121 adapted to the first cutter assembly 230 also moves toward the direction close to the rolled material. When the circular knife 237 and the above-mentioned pressure roller 121 are in contact with each other, the rolled material is cut into strips of different widths in the length direction through the cooperation of multiple circular knives 237 and pressure rollers 121.

[0076] See also Figures 10 and 11As shown, the first heating component 240 includes a side mounting plate 241, a second cylinder 242, a first cooling tube 243, a first heating lamp 244 and a first protective cover 245. The side mounting plate 241 is fixed to the lower end of the tool holder base plate 232, the second cylinder 242 is fixed to one side of the side mounting plate 241, the first cooling tube 243 is fixed to the output end of the second cylinder 242, the first heating lamp 244 is fixed to the end of the first cooling tube 243 away from the second cylinder 242, and the first protective cover 245 is fixed on the first cooling tube 243 and is located on the outside of the first heating lamp 244.

[0077] Furthermore, the second cylinder 242 and the air supply module are also connected through a pipeline.

[0078] It should be noted that, in this embodiment, there are two first protective covers 245 , and heat collecting grooves are provided at one end of the two first protective covers 245 close to the roll material. Through the cooperation of the first protective covers 245 , the heating effect of the first heating lamp 244 on the roll material can be improved.

[0079] In this embodiment, when the roll material needs to be cut according to the width size of the PCB board, the position of the first cutter assembly 230 is adjusted by the push plate assembly 220. Since the side mounting plate 241 is fixed to one end of the tool holder base plate 232, the side mounting plate 241 will move synchronously with the tool holder base plate 232, and the second cylinder 242 is started, so that the output end of the second cylinder 242 is pushed out. Through the fixed connection between the second cylinder 242 and the first cooling tube 243 and the fixed connection between the first cooling tube 243 and the first heating lamp 244, the second cylinder 242 drives the first cooling tube 243 and the first heating lamp 244 to move toward the direction of the roll material, and the first heating lamp 244 is started, so that the first heating lamp 244 releases heat, and the roll material is heated by the first heating lamp 244, thereby reducing the generation of PP powder during the cutting process and reducing the undesirable phenomenon of white edges of PP cuts, thereby improving product quality.

[0080] See also Figures 14 to 16 As shown, the second cutter assembly 310 includes a lower cutter base plate 311, a lower cutter 312, a third cylinder 313, an upper cutter base plate 314 and an upper cutter 315.

[0082] In this embodiment, when it is necessary to cut the strip material in the width direction, the third cylinder 313 is started to move the output end of the third cylinder 313. Through the fixed connection between the third cylinder 313 and the upper knife base plate 314 and the fixed connection between the upper knife base plate 314 and the upper cutter 315, the third cylinder 313 drives the upper knife base plate 314 and the upper cutter 315 to move toward the direction close to the strip material.
