Description

Technical Field

[0001] The invention belongs to the technical field of copper clad laminate production, and in particular relates to automated processing equipment for high temperature resistant copper clad laminates. Background Art

[0002] High temperature resistant copper clad laminate, also known as substrate, is a plate-like material made by impregnating reinforcing material with glue made of resin, covering one or both sides with copper foil, and hot pressing. It is called copper clad laminate. In the production process of high temperature resistant copper clad laminate, hot pressing process operation is indispensable. Traditional hot pressing device for copper clad laminate production needs to cut copper foil into fixed size and manually place it before hot pressing operation. The operation is cumbersome and the workload of workers is large. Therefore, it is necessary to update an automated processing equipment for copper clad laminate production in time.

[0003] After searching, in the prior art, the announcement number: CN220517780U, the announcement date: 2024-02-23, discloses a hot pressing device for copper clad laminate production, wherein the fixed shell includes a bottom plate, a front baffle, a left baffle, a right baffle, a rear baffle and a top plate, and also includes a spring, an exhaust groove, a hollow top piece, a heating bottom plate, a square groove, a bevel blade, a round hole, a cylindrical groove, a round rod, a first hydraulic cylinder, a first telescopic rod, a first push baffle, a first pressure sensor, a second hydraulic cylinder, a second telescopic rod, a second push baffle, a second pressure sensor, a third hydraulic cylinder, a third telescopic rod, a third push baffle and a third pressure sensor.

[0004] However, the device still has the following defects: although it can prevent the copper clad laminate from moving horizontally in the other two directions, thus avoiding an increase in the defective rate of production, and can facilitate the unloading of the hot-pressed copper clad laminate, before the device can be used to process the high-temperature resistant copper clad laminate, the cut copper foil needs to be manually placed into the device before the hot pressing operation can be carried out, resulting in low processing efficiency and a large workload for workers.

[0018] The beneficial effects of the present invention are:

[0019] 1. The first motor drives two groups of receiving rollers to rotate, and the upper copper foil and the lower copper foil are synchronously wound. The glue brushing component is used to brush glue on the pressing area of ​​the lower copper foil. The two groups of copper foils are hot-pressed by the hot-pressing mechanism to complete the processing and production of the high-temperature resistant copper clad laminate. After the processing, the finished high-temperature resistant copper clad laminate is automatically transferred to the conveyor belt for transportation through the transfer mechanism. After the processing of the high-temperature resistant copper clad laminate, the two groups of copper foil wastes are continuously wound by the receiving roller. The device does not need to manually place the copper foil, and can automatically perform continuous copper foil transportation, hot pressing, and finished product transfer operations, which effectively improves the processing efficiency and reduces the workload of workers.

[0020] 2. The upper copper foil and the lower copper foil are kept flat during the transportation process through two sets of tensioning mechanisms. The second motor drives the linkage shaft to rotate, so that the two sets of active bevel gears rotate synchronously, thereby making the two sets of lead screws rotate synchronously to achieve the height adjustment of the second tensioning roller. When the lower copper foil is brushed with glue, the second tensioning roller moves upward to avoid the upper copper foil from blocking the lower copper foil. When the two sets of copper foils are hot-pressed, the second tensioning roller drives the upper copper foil to move downward to fit with the surface of the lower copper foil, thereby improving the hot-pressing fit and effectively avoiding the deformation of the copper foil during the hot-pressing process.

[0021] 3. The press glue is pumped into the tee through a group of first spiral telescopic tubes, and then into several groups of glue discharging mechanisms. The press glue is squeezed out to the surface of the lower copper foil through the glue discharging pipes. The glue discharging mechanisms are driven to move horizontally by two groups of second cylinders, so that the pressed area of ​​the lower copper foil is covered with press glue. The glue discharging mechanisms are reset by the second cylinders. While the glue discharging mechanisms are moving, the two groups of scraping blocks are synchronously moved to scrape the press glue flat, so that the press glue is evenly distributed. In the process of moving, the excess press glue is pushed to the side wall of the scraping block, and the excess press glue is recycled by the recycling mechanism, which improves the hot pressing effect and effectively saves energy.

[0022] 4. The third cylinder drives the hot pressing block to move downward, driving the pressing areas of the two groups of copper foils to contact the surface of the hot pressing seat. The hot pressing block continues to move downward, so that the two groups of copper foils complete the hot pressing operation. At the same time, the high-temperature resistant copper clad laminate that has completed the pressing operation is cut by the cutting knife. The cut high-temperature resistant copper clad laminate stays on the hot pressing seat. While the hot pressing operation is buffered by the elastic potential energy of the spring, the processed high-temperature resistant copper clad laminate can be driven to rise to the top of the hot pressing tank, which is convenient for the transfer mechanism to transfer it, thereby improving the safety and smoothness of the processing process of the device.

[0057] Specifically, the hot pressing block 1103 moves downward, driving the pressing areas of the two groups of copper foils to contact the surface of the hot pressing seat 104. The hot pressing block 1103 continues to move downward, so that the two groups of copper foils complete the hot pressing operation. At the same time, the high-temperature resistant copper clad laminate that has completed the pressing operation is cut by the cutting knife 106. The cut high-temperature resistant copper clad laminate stays on the hot pressing seat 104 and is driven to rise to the top of the hot pressing tank 101 by the elastic potential energy of the spring 105, so that the transfer mechanism 19 can transfer it. The waste of the two groups of copper foils after cutting is rolled up by two groups of receiving rollers 4.

[0058] The working principle of the automatic processing equipment for high temperature resistant copper clad laminate proposed by the present invention is as follows:

[0059] The first motor 8 drives the two groups of receiving rollers 4 to rotate, and the upper copper foil and the lower copper foil are synchronously wound. The two groups of tensioning mechanisms 9 are used to keep the upper copper foil and the lower copper foil flat during the transportation process. The second motor 907 drives the linkage shaft 9013 to rotate, so that the two groups of active bevel gears 9011 rotate synchronously, thereby making the two groups of lead screws 909 rotate synchronously, and the height of the second tensioning roller 905 is adjusted. When the lower copper foil is brushed with glue, the second tensioning roller 905 moves upward to avoid the upper copper foil from blocking the lower copper foil. When the two groups of copper foils are hot-pressed, the second tensioning roller 905 drives the upper copper foil to move downward to fit with the surface of the lower copper foil, thereby improving the fit of the hot pressing and effectively avoiding deformation of the copper foil during the hot pressing process.

[0060] The electric turntable 13 drives the linkage frame 15 to rotate, so that the glue brushing assembly 20 rotates to the top of the lower copper foil, and the first cylinder 14 drives the glue brushing assembly 20 to move downward so that the glue brushing box 2001 contacts the lower copper foil, and the press glue is driven by the liquid pump 21 to enter the three-way pipe 2007 through a group of first spiral telescopic pipes 2004, and then enters a plurality of groups of glue discharging mechanisms 2003, and squeezes the press glue to the surface of the lower copper foil through the glue discharging pipe 20032, and then passes through the two groups of second cylinders 200 2 drives the glue discharging mechanism 2003 to move horizontally, so that the area where the lower copper foil is pressed is covered with the pressing glue, and then the glue discharging mechanism 2003 is reset by the second cylinder 2002. While the glue discharging mechanism 2003 moves, the two groups of glue scraping blocks 20033 move synchronously to scrape the pressing glue flat, so that the pressing glue is evenly distributed, and in the process of moving, the excess pressing glue is pushed to the side wall of the glue scraping block 20033, and the excess pressing glue is recycled by the recycling mechanism 2006.

[0061] The air inlet end of the vacuum pump 16 is interconnected with the second exhaust pipe 20068 through the three-way solenoid valve 17, so that a vacuum is formed in the vacuum box 20066 after the vacuum pump 16 is turned on, thereby forming a negative pressure inside the scraper block 20033 that is interconnected with the recovery pipe 20061, so that the excess pressed glue accumulated on the side wall of the scraper block 20033 can enter the scraper block 20033 through the glue suction hole 20034, and finally enter the recovery pipe 20061 through the glue suction pipe 20063, and the recovered pressed glue is filtered through the filter 20064. The air guide membrane 20067 can prevent the pressed glue from entering the vacuum box 20066. The filtered pressed glue is extracted into a group of first spiral telescopic tubes 2004 through the circulation pump 20062, and finally enters the glue outlet mechanism 2003 for recycling.

[0062] The third cylinder 1102 drives the hot pressing block 1103 to move downward, driving the pressing areas of the two groups of copper foils to contact the surface of the hot pressing seat 104. The hot pressing block 1103 continues to move downward, so that the two groups of copper foils complete the hot pressing operation. At the same time, the high-temperature resistant copper clad laminate that has completed the pressing operation is cut by the cutting knife 106. The cut high-temperature resistant copper clad laminate stays on the hot pressing seat 104 and is driven to rise to the top of the hot pressing tank 101 by the elastic potential energy of the spring 105, so that the transfer mechanism 19 can transfer it. The waste materials of the two groups of copper foils after cutting are rolled up by two groups of receiving rollers 4.

[0063] The linkage frame 15 is driven to rotate by the electric turntable 13, so that the transfer mechanism 19 is rotated to the top of the high-temperature resistant copper-clad laminate. The transfer mechanism 19 is driven downward by the first cylinder 14 to make the bottom end of the suction cup 1903 contact the high-temperature resistant copper-clad laminate. The air inlet end of the vacuum pump 16 is connected to the first exhaust pipe 1902 through the three-way solenoid valve 17, so that negative pressure is formed inside the transfer box 1901, and negative pressure is formed on the lower surface of several groups of suction cups 1903, so that the clamping operation of the high-temperature resistant copper-clad laminate can be realized. Then, the transfer mechanism 19 is driven to rotate to the top of the conveyor belt by the electric turntable 13, and the processed high-temperature resistant copper-clad laminate is placed on the conveyor belt for transportation, thereby realizing the clamping and transfer operations of the high-temperature resistant copper-clad laminate.
