Description

Technical Field

[0001] The present invention belongs to the technical field of hot presses, and particularly relates to a heat preservation and energy-saving device for a copper clad laminate hot press. Background Art

[0002] A copper clad laminate is a product made by using wood pulp paper or fiberglass cloth as a reinforcing material, impregnating it with resin, and covering one or both sides with copper foil and then hot pressing. When it is used in the production of multi-layer boards, it is also called a core board.

[0003] At present, during the production process of copper clad laminates, they need to be hot pressed and formed by a hot press. During the use of the hot press, since the hot press plate is exposed to the outside, the hot press plate will come into contact with the external air, resulting in heat loss of the hot press plate and causing heat waste.

[0004] In view of the above technical problems, the applicant has retrieved some prior arts to achieve heat preservation and energy saving of the hot press. For example, a heat preservation and energy-saving device for a copper clad laminate hot press with the patent publication number CN217124243U. Its main technical means is to place the copper clad laminate between two corresponding press plates, start the cylinder switch, the piston of the cylinder drives the press plate to move downward, thereby squeezing multiple press plates, and hot pressing the copper clad laminate through the electric heating plate. After the hot pressing is completed, start the motor switch, the output shaft of the motor drives the rotating rod to rotate, the rotating rod drives the corresponding rotating shaft to rotate through the transmission connection of the first pulley, the second pulley and the belt, the rotating rotating shaft drives another rotating shaft to rotate simultaneously through the meshing of the driving gear and the internal gear ring, and the rotating rotating shaft cooperates with the conversion box through the spiral blade, so as to be able to extract the water in the box through the water conduit, convert the heat on the press plate, and flow into the box through the water inlet hole for energy recovery. After the applicant's analysis, the disadvantages of this technical solution are as follows: The water in the above solution can absorb the heat on the electric heating plate, which reduces the heat on the electric heating plate. In this way, when hot pressing is carried out next time, the electric heating plate still needs to be preheated to provide additional heat, resulting in heat loss of the electric heating plate and affecting the hot pressing efficiency. Summary of the Invention

[0008] As a preference of the above technical solution, a vacuum pump is installed outside the sealing cover, several air holes are formed in the sealing cover, the vacuum pump is communicated with the several air holes, the output end of the vacuum pump is connected with a heat preservation box, and an air extraction pump I is connected to the heat preservation box, and the air extraction pump I is communicated with the telescopic cavity.

[0009] As a preference of the above technical solution, the length of the lower pressing plate is greater than the length of the lower hot pressing plate, and the two through grooves are located at both ends of the long side of the lower pressing plate.

[0010] As a preference of the above technical solution, two inclined grooves are symmetrically formed at the top of the telescopic cavity, and the two inclined grooves are located below the two through grooves.

[0013] As a preference of the above technical solution, one side of the movable cover is in sealed contact with one side of the sealing cover, and the side of the movable cover close to the through groove is communicated with the through groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, after hot pressing is completed, the lower hot pressing plate and several hot supporting plates move downward into the telescopic cavity, and the hot-pressed copper clad laminate is taken out through the through groove. During this process, the top and bottom of the lower hot pressing plate or the hot supporting plate near the through groove may come into contact with the external air. However, during the process of taking out the copper clad laminate, the copper clad laminate blocks the top and bottom of the lower hot pressing plate or the hot supporting plate, so that the time for the lower hot pressing plate or the hot supporting plate to contact the external air is relatively short, effectively avoiding the long-term contact between the external air and the lower hot pressing plate or the hot supporting plate, making the heat on the lower hot pressing plate or the hot supporting plate not easily lost, avoiding heat waste, and enabling the lower hot pressing plate or the hot supporting plate not to require long-term preheating during subsequent hot pressing, thus effectively avoiding the reduction of hot pressing efficiency; 2. In the present invention, during the hot pressing process, since the sealing cover wraps the lower hot pressing plate or the hot supporting plate, the heat loss of the lower hot pressing plate or the hot supporting plate is effectively avoided; after hot pressing is completed, the lower hot pressing plate enters the telescopic cavity, while the hot supporting plate is still wrapped by the sealing cover; before hot pressing, the substrate and copper foil are placed on the lower hot pressing plate or the hot supporting plate through the through groove; this makes the lower hot pressing plate or the hot supporting plate always in an approximately sealed state whether before hot pressing, during hot pressing, or after hot pressing is completed, thus effectively avoiding the contact between the lower hot pressing plate or the hot supporting plate and the external air, and further effectively avoiding the heat loss of the lower hot pressing plate or the hot supporting plate; 3. In the present invention, through the combined use of a vacuum pump, an air extraction pump I, and a heat preservation box, the high-temperature gas extracted from the inside of the sealing cover enters the heat preservation box for heat preservation. When hot pressing is completed, the high-temperature gas in the heat preservation box is pumped into the telescopic cavity by the air extraction pump I, so that the lower hot pressing plate or the hot supporting plate entering the telescopic cavity comes into contact with the high-temperature gas, thereby insulating the lower hot pressing plate or the hot supporting plate and avoiding the heat loss of the lower hot pressing plate or the hot supporting plate. During subsequent hot pressing, the lower hot pressing plate or the hot supporting plate does not need to be preheated again, thus improving the hot pressing efficiency; 4. In the present invention, the hot air in the telescopic cavity moves upward and is discharged from the two inclined grooves, so that the hot air blocks the external air from entering the space between the lower hot pressing plate, the hot supporting plate, and the two hot supporting plates through the through groove, thereby further avoiding the contact between the lower hot pressing plate and the hot supporting plate and the external air, and further effectively avoiding the reduction of hot pressing efficiency; 5. In the present invention, by recovering the heat inside the hot-pressed copper clad laminate, the waste of heat inside the copper clad laminate is avoided, the heat loss inside the copper clad laminate is effectively avoided, so that the heat inside the copper clad laminate can be fully recovered. At the same time, the hot air discharged through the inclined groove enters the movable cover, and both the hot air and the heat inside the copper clad laminate are recovered, and the heat loss is relatively small, making the heat fully utilized, thereby further avoiding the heat loss on the lower hot pressing plate and the hot supporting plate, and further avoiding the reduction of hot pressing efficiency.

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0019] As Figures 1 - 3 shown, a heat preservation and energy-saving device for a copper clad laminate hot press includes an upper pressing plate 1, a lower hot pressing plate 2, a heat supporting plate 3, a first telescopic member 4, a guide rod 9, a connecting column 18 and a top plate 19. The device further includes: A sealing cover 5, with a sealing cover 5 sleeved outside several heat supporting plates 3. The sealing cover 5 completely wraps several heat supporting plates 3 and the lower hot pressing plate 2. Through grooves 52 are opened on opposite sides of the periphery of the sealing cover 5; A lower pressing plate 7, with a base 6 provided below the sealing cover 5. A telescopic cavity 61 is opened at the top of the base 6. A second telescopic member 8 is installed in the telescopic cavity 61. The output end of the second telescopic member 8 is provided with a lower pressing plate 7. The lower pressing plate 7 abuts against the bottom of the lower hot pressing plate 2. Several guide rods 9 penetrate through the lower pressing plate 7 and are fixed at the bottom of the telescopic cavity 61.

[0020] In a case of this embodiment, the first telescopic member 4, the lower hot pressing plate 2, the heat supporting plate 3 and the second telescopic member 8 are all prior arts, and the present application does not improve them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present application.

[0021] In actual application of this embodiment, during hot pressing, the substrate and the copper foil are placed between two adjacent hot support plates 3. The upper pressing plate 1 presses downwards, and together with the hot support plates 3 and the lower hot pressing plate 2 providing heat sources, the substrate and the copper foil are pressed into a copper clad laminate. After hot pressing is completed, the upper pressing plate 1 and the lower pressing plate 7 move downwards. Among them, the lower pressing plate 7 moves downwards at a faster speed than the upper pressing plate 1, so that the copper clad laminate between two adjacent hot support plates 3 is no longer restricted from moving. When the lower hot pressing plate 2 moves down into the telescopic cavity 61 and its top is flush with the top of the base 6, the lower pressing plate 7 stops moving. Then, the copper clad laminate above the lower hot pressing plate 2 is taken out through the through groove 52. In this way, the remaining copper clad laminates are taken out from other hot support plates 3. During this process, the top and bottom of the lower hot pressing plate 2 or the hot support plate 3 near the through groove 52 may come into contact with the external air. However, during the process of taking out the copper clad laminate, the copper clad laminate blocks the top and bottom of the lower hot pressing plate 2 or the hot support plate 3, so that the time for the lower hot pressing plate 2 or the hot support plate 3 to come into contact with the external air is relatively short, effectively avoiding the long-term contact between the external air and the lower hot pressing plate 2 or the hot support plate 3, making the heat on the lower hot pressing plate 2 or the hot support plate 3 not easy to dissipate, avoiding heat waste, and enabling the lower hot pressing plate 2 or the hot support plate 3 not to require long-term preheating during subsequent hot pressing, thus effectively avoiding the reduction of hot pressing efficiency; During the hot pressing process, since the sealing cover 5 wraps the lower hot pressing plate 2 or the hot support plate 3, it effectively avoids the heat loss of the lower hot pressing plate 2 or the hot support plate 3; after hot pressing is completed, the lower hot pressing plate 2 enters the telescopic cavity 61, while the hot support plate 3 is still wrapped by the sealing cover 5; before hot pressing, the substrate and the copper foil are placed on the lower hot pressing plate 2 or the hot support plate 3 through the through groove 52; in this way, the lower hot pressing plate 2 or the hot support plate 3 is always in an approximately sealed state whether before hot pressing, during hot pressing, or after hot pressing is completed, thus effectively avoiding the contact between the lower hot pressing plate 2 or the hot support plate 3 and the external air, and further effectively avoiding the heat loss of the lower hot pressing plate 2 or the hot support plate 3.

[0022] Furthermore, the height of the through groove 52 is greater than the thickness of the copper clad laminate after hot pressing is completed. A third telescopic member 16 is installed on the base 6, and a push plate 17 is provided at the output end of the third telescopic member 16. The push plate 17 just fits into one of the through grooves 52, and the push plate 17 completely blocks this through groove 52.

[0023] In one case of this embodiment, the third telescopic member 16 can be a cylinder or other components capable of telescopic driving.

[0024] In actual application of this embodiment, before hot pressing, the substrate and the copper foil can be pushed above the lower hot pressing plate 2 or the heat supporting plate 3 by the third telescopic member 16 and the pushing plate 17. After hot pressing is completed, the third telescopic member 16 and the pushing plate 17 can push the hot-pressed copper clad laminate out of the lower hot pressing plate 2 or the heat supporting plate 3. In this way, the placing speed of the substrate and the copper foil is increased, and the taking-out speed of the copper clad laminate is increased, thereby further reducing the contact time between the lower hot pressing plate 2 or the heat supporting plate 3 and the external air, making it more difficult for the heat on the lower hot pressing plate 2 or the heat supporting plate 3 to escape, and effectively avoiding the reduction of hot pressing efficiency.

[0025] As Figure 1 and Figure 2 shown, a vacuum pump 10 is installed outside the sealing cover 5. A plurality of air holes 51 are formed in the sealing cover 5. The vacuum pump 10 is communicated with the plurality of air holes 51. The output end of the vacuum pump 10 is connected to a heat preservation box 20. A first air extraction pump 11 is connected to the heat preservation box 20, and the first air extraction pump 11 is communicated with the telescopic cavity 61.

[0026] In one case of this embodiment, the vacuum pump 10, the first air extraction pump 11, and the heat preservation box 20 are all prior arts, and this application does not improve them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of this application.

[0027] In actual application of this embodiment, the sealing cover 5 is evacuated by the vacuum pump 10 in cooperation with the plurality of air holes 51, which effectively avoids the generation of bubbles between layers during the pressing of the copper clad laminate and ensures the quality of the copper clad laminate. During the evacuation process, the extracted gas is high-temperature gas and enters the heat preservation box 20 for heat preservation. When hot pressing is completed, the high-temperature gas in the heat preservation box 20 is pumped into the telescopic cavity 61 by the first air extraction pump 11, so that the lower hot pressing plate 2 or the heat supporting plate 3 entering the telescopic cavity 61 contacts the high-temperature gas, thereby insulating the lower hot pressing plate 2 or the heat supporting plate 3 and avoiding the heat loss of the lower hot pressing plate 2 or the heat supporting plate 3. During subsequent hot pressing, the lower hot pressing plate 2 or the heat supporting plate 3 does not need to be preheated, thereby improving the hot pressing efficiency; Since the vacuum pump 10 evacuates the inside of the sealing cover 5 to a vacuum state, when the space between the lower hot pressing plate 2 and the heat supporting plate 3 and the two heat supporting plates 3 is located at the through groove 52, due to the negative pressure state inside the sealing cover 5, external air will enter the space between the lower hot pressing plate 2 and the heat supporting plate 3 and the two heat supporting plates 3 through the through groove 52, thereby exchanging heat with the heat on the lower hot pressing plate 2 or the heat supporting plate 3, resulting in the heat loss of the lower hot pressing plate 2 or the heat supporting plate 3. At this time, after the lower hot pressing plate 2 and the heat supporting plate 3 enter the telescopic cavity 61, the high-temperature gas in the telescopic cavity 61 contacts the lower hot pressing plate 2 and the heat supporting plate 3, so that the surface temperature of the lower hot pressing plate 2 and the heat supporting plate 3 rises, effectively avoiding the heat loss on the lower hot pressing plate 2 or the heat supporting plate 3; In addition, a heating structure, such as an electromagnetic heating mechanism, can be added inside the incubator 20. Before hot pressing, the external air is drawn into the incubator 20 by the first air extraction pump 11, and the air is heated to serve as a reserve heat source. In this way, a relatively large amount of hot air enters the expansion cavity 61 subsequently. Moreover, during the next hot pressing, after the hot air follows the lower hot pressing plate 2 and the hot support plate 3 upward, the pressure inside the sealing cover 5 will remain in a balanced state or a high-pressure state. During hot pressing, the hot air inside the sealing cover 5 is drawn into the incubator 20 by the vacuum pump 10, so that the heat source is circulated, effectively avoiding the heat loss of the lower hot pressing plate 2 or the hot support plate 3, and thus preventing the reduction of hot pressing efficiency.

[0028] Furthermore, the length of the lower pressing plate 7 is greater than that of the lower hot pressing plate 2, and the two through grooves 52 are located at both ends of the long side of the lower pressing plate 7.

[0029] Furthermore, two inclined grooves 63 are symmetrically formed at the top of the expansion cavity 61, and the two inclined grooves 63 are located below the two through grooves 52.

[0030] In actual application of this embodiment, since the length of the lower pressing plate 7 is greater than that of the lower hot pressing plate 2, after the lower hot pressing plate 2 and the hot support plate 3 enter the expansion cavity 61, the hot air inside the expansion cavity 61 can move upward to contact the lower hot pressing plate 2 and the hot support plate 3, and the hot air can be discharged through the two inclined grooves 63 when moving upward, thereby blocking the external air from entering the space between the lower hot pressing plate 2 and the hot support plate 3 and the two hot support plates 3 through the through grooves 52, further avoiding the contact between the lower hot pressing plate 2 and the hot support plate 3 and the external air, and effectively preventing the reduction of hot pressing efficiency.

[0031] As Figures 1 - 3 shown, an installation cavity 62 is formed on one side of the top of the base 6 away from the push plate 17. A net plate 12 is installed at the top of the installation cavity 62, and the net plate 12 is flush with the top of the base 6. A wind collecting cover 13 is arranged at the bottom of the net plate 12, and a second air extraction pump 14 is installed at the bottom of the wind collecting cover 13. The second air extraction pump 14 is communicated with the expansion cavity 61.

[0032] In actual application of this embodiment, when the copper clad laminate after hot pressing is pushed out and moves onto the net plate 12, since the copper clad laminate contains a certain amount of heat inside after hot pressing, this part of the heat will contact the air, resulting in heat waste. At this time, the heat inside the copper clad laminate can be drawn into the expansion cavity 61 through the second air extraction pump 14 and the wind collecting cover 13. On the one hand, the heat inside the copper clad laminate is recovered to avoid heat waste, and on the other hand, the copper clad laminate is quickly cooled, so that it is not easy for workers to get burned when taking the copper clad laminate.

[0033] Furthermore, a movable cover 15 is installed on the top of the base 6, and the movable cover 15 covers the top of the net plate 12.

[0034] Furthermore, one side of the movable cover 15 is in sealing contact with one side of the sealing cover 5, and the side of the movable cover 15 close to the through groove 52 is in communication with the through groove 52.

[0035] In practical application of this embodiment, the movable cover 15 can effectively prevent the copper clad laminate on the mesh plate 12 from contacting the external air, effectively avoid heat loss inside the copper clad laminate, enable the heat inside the copper clad laminate to be fully recovered. At the same time, the hot air discharged through the inclined groove 63 enters the movable cover 15, and both the hot air and the heat inside the copper clad laminate are recovered, with relatively less heat loss, enabling the heat to be fully utilized, thereby further preventing heat loss on the lower hot pressing plate 2 and the heat supporting plate 3, and further avoiding a reduction in the hot pressing efficiency. At the same time, when the lower hot pressing plate 2 and several heat supporting plates 3 move downward, the space between the lower hot pressing plate 2 and the heat supporting plate 3 and between the two heat supporting plates 3 is in a negative pressure state, and a part of the heat in the movable cover 15 will enter the space between the lower hot pressing plate 2 and the heat supporting plate 3 and between the two heat supporting plates 3, thereby further preventing heat loss on the lower hot pressing plate 2 and the heat supporting plate 3.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
