Description

Technical Field

[0001] The utility model belongs to the technical field of copper clad laminate production, and in particular relates to a material preparation device for copper clad laminate production. Background Art

[0002] Copper clad laminate is a plate-like material made by impregnating electronic glass fiber cloth or other reinforcing materials with resin, covering one or both sides with copper foil and hot pressing. It is referred to as copper clad laminate. Printed circuit boards of various forms and functions are made by selectively processing, etching, drilling and copper plating on copper clad laminates to make different printed circuits. It mainly plays the role of interconnection, insulation and support for printed circuit boards, and has a great influence on the transmission speed, energy loss and characteristic impedance of signals in the circuit. Therefore, the performance, quality, processability, manufacturing level, manufacturing cost, long-term reliability and stability of printed circuit boards depend to a large extent on copper clad laminates. Among them, in the production process of copper clad laminates, the semi-cured sheets as raw materials need to be prepared by quantitative cutting.

[0003] Problems with existing technologies:

[0004] In the process of cutting the semi-cured sheet, the existing cutting machines are equipped with a belt conveyor at the output position to transport the cut semi-cured sheet, but there is no corresponding fixing mechanism at this position to fix the semi-cured sheet to be cut, so that the semi-cured sheet is prone to slight slippage under the action of shear stress during cutting, resulting in deviation in the size of the copper clad laminate raw material. However, if the traditional fixing equipment is used in conjunction with the belt, it is necessary to overcome the problem of deformation of the profile surface due to pressure. The main reason is that the belt is a soft material. When the fixing equipment applies pressure to the profile, the belt surface will also be stressed and deformed, causing deformation of the profile surface. Utility Model Content

[0005] The purpose of the utility model is to provide a material preparation device for copper clad laminate production, which can ensure that the part of the semi-cured sheet to be cut will not slip slightly during cutting, and the adsorption-type fixing means ensures the surface quality of the profile.

Detailed Embodiment

[0025] In order to make the purpose and advantages of the utility model clearer, the following specifically describes the utility model with reference to the embodiments. It should be understood that the following text only describes one or several specific implementation manners of the utility model, and does not strictly limit the specific protection scope claimed by the utility model.

[0026] As Figures 1-4As shown, a material preparation device for copper clad laminate production includes a prepreg feeding mechanism 1 for conveying prepregs, a cutting mechanism 2 for cutting the prepregs is arranged on one side of the prepreg feeding mechanism 1, a pressure strip 201 and a cutting tool 202 assembled by a lifting mechanism are arranged inside the cutting mechanism 2, and a stable unloading table 3 for fixing the cut part during cutting is arranged on the side of the cutting mechanism 2 away from the prepreg feeding mechanism 1.

[0027] According to the above structure, the prepreg roll is transported from the prepreg feeding mechanism 1 to the cutting mechanism 2. When it is transported to a specified length, the transport is stopped, the pressure strip 201 moves down and presses one side of the prepreg, and the cutting tool 202 moves down to directly cut.

[0028] See attached Figure 2 The stable unloading platform 3 includes a belt frame 301, a partition 321 is integrally arranged in the middle of the belt frame 301, and perforated belts 322 for transportation are assembled on both sides thereof, and active rollers 303 for driving the perforated belts 322 are assembled through the two ends of the belt frame 301, and a driving motor 302 is fixedly installed on the outer wall of one end of the belt frame 301, and a driven roller 323 is assembled through the middle of the belt frame 301.

[0029] See attached Figure 2 Air compartments 304 are fixedly installed on both sides of the inner part of the belt frame 301 near the cutting mechanism 2, and sealing strips 305 are installed on both sides of the surface edge of the air compartment 304. Instantaneous suction pipes 306 are installed inside the air compartment 304, and suction holes are arranged in an array on the top of the surface of the instantaneous suction pipe 306.

[0030] See attached Figure 2 and Figure 4 The outer walls of both sides of the belt frame 301 are provided with side frames 307, and an open gas tank 308 is fixedly installed at one end of the inner side of the side frame 307. The interior of the open gas tank 308 is telescopically assembled with a piston member 309, and the end of the instantaneous suction pipe 306 is connected to the outer wall of one end of the open gas tank 308, and the outer wall of one end of the open gas tank 308 is fixedly connected with an air intake pipe, and a one-way valve is installed inside the instantaneous suction pipe 306 and the end of the air intake pipe close to the open gas tank 308.

[0031] See attached Figure 3 and Figure 4The piston member 309 extends out of the open gas tank 308, and the end thereof is fixedly connected to a guide rod 310 on both sides. A gear rod 313 is integrally provided on the side wall of one end of the guide rod 310. A guide sleeve 311 is fixedly provided on both sides of the outer wall of the open gas tank 308. The guide rod 310 movably penetrates the corresponding guide sleeve 311, and a spring 312 is provided between the end of the guide rod 310 and the side wall of the guide sleeve 311. A driving shaft 316 is rotatably assembled at the top and bottom ends of the other end of the inner side frame 307, and a gear 313 is slidably provided on the outer surface of the middle part of the driving shaft 316. 18, the gear 318 is detachably meshed with the corresponding gear rod 313, and the two gears 318 are connected by a connecting frame 319, the other end of the inner side of the side frame 307 is fixedly installed with a cylinder 320, and the telescopic output end of the cylinder 320 is fixedly connected to the connecting frame 319, and one end of the inner side of the side frame 307 is rotatably installed with a double sprocket shaft 314, the double sprocket shaft 314 is connected to one end of the driven roller 323 through a sleeve chain 1 315, and one end of the two driving shafts 316 is connected to the corresponding double sprocket shaft 314 through a sleeve chain 2 317.

[0032] According to the above structure, before the semi-cured sheet is cut, the driving motor 302 drives the perforated belt 322 to operate at the same time, so that the semi-cured sheet is transported smoothly. During this process, the driven roller 323 drives the double sprocket shaft 314 to rotate through the chain 1 315, and the double sprocket shaft 314 drives the two driving shafts 316 to rotate at the same time through the chain 2 317. The driving shaft 316 drives the gear 318 to rotate and the piston member 309 moves linearly through the meshing of the gear 318 and the toothed rod 313. Relative movement will occur between the guide rod 310 and the guide sleeve 311 and the spring 312 will be squeezed at the same time, and then the transportation will be stopped. The lifting mechanism in the cutting mechanism 2 and the cylinder 320 will operate at the same time. When the cutting tool 202 starts to move downward, the cylinder 320 operates and separates the gear 318 and the toothed rod 313 laterally through the connecting frame 319, and the piston member 309 loses its fixation, and then under the elastic force of the compressed spring 312, The piston member 309 moves quickly, causing negative pressure to be generated inside the open gas tank 308, and the negative pressure acts on the instantaneous suction tube 306 to generate suction, which ultimately generates suction inside the air compartment 304. The suction acts directly on the semi-cured sheet through the perforations of the perforated belt 322, so that the other side of the semi-cured sheet can be adsorbed and fixed during cutting. The above process can fix both sides of the semi-cured sheet when it is cut, ensuring that the part of the semi-cured sheet to be cut will not slip slightly during cutting, thereby ensuring the stability of the material during cutting. In addition, the adsorption-type fixing means cooperates with the perforated belt 322, which will not cause the semi-cured sheet to deform due to pressing, thereby ensuring the surface quality of the profile. Finally, the adsorption structure is triggered during cutting and stores energy during transportation, and the energy storage process is completed by utilizing the kinetic energy of the perforated belt 322 during operation, without generating excessive power consumption.

[0033] The working principle of the utility model is as follows: The prepreg coil is transported by the prepreg feeding mechanism 1 to the cutting mechanism 2. When it is transported to the specified length, the transportation stops, the pressing strip 201 moves downward to hold one side of the prepreg, and the cutting tool 202 moves downward to directly perform cutting. Before the prepreg is cut, the driving motor 302 drives the perforated belt 322 to operate simultaneously, so that the prepreg is smoothly transported. During this process, the driven roller 323 drives the double sprocket shaft 314 to rotate through the first chain 315, and the double sprocket shaft 314 drives two driving shafts 316 to rotate simultaneously through the second chain 317. The driving shaft 316 drives the gear 318 to rotate, and through the meshing of the gear 318 and the toothed rod 313, the piston member 309 moves linearly. Relative movement occurs between the guide rod 310 and the guide sleeve 311, and the spring 312 is compressed simultaneously. Immediately afterwards, the transportation stops, and the lifting mechanism and the cylinder 320 in the cutting mechanism 2 operate simultaneously. When the cutting tool 202 starts to move downward, the cylinder 320 operates and separates the gear 318 and the toothed rod 313 laterally through the connecting frame 319. The piston member 309 loses its fixation, and then under the elastic force of the spring 312 in the compressed state, the piston member 309 moves rapidly, causing a negative pressure inside the open-type air tank 308. The negative pressure acts on the instantaneous suction pipe 306 and causes it to generate suction. Finally, suction is generated inside the air separation chamber 304. This suction directly acts on the prepreg through the perforations of the perforated belt 322, so that the other side of the prepreg can be adsorbed and fixed during cutting.

[0034] The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model. The structures, devices, and operation methods not specifically described and explained in the utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
