Description

Technical Field

[0001] The invention relates to the technical field of circuit board manufacturing equipment, in particular to a pressing device for manufacturing a multi-layer circuit board. Background Art

[0002] Circuit boards can be divided into single-layer boards, double-layer boards and multi-layer boards according to their structures. Single-layer boards refer to boards with only one circuit layer on the surface of the substrate, double-layer boards refer to boards with circuit layers on both sides of the substrate, and multi-layer boards are made by adding copper foil layers to the outside of the core board using prepregs on the basis of double-layer boards (in this case, the double-layer boards are also called core boards), thus making multi-layer circuit boards. It should be noted that the semi-finished multi-layer boards are only formed by sequentially pasting prepregs and copper foil layers on the core board. The semi-finished multi-layer boards need to be placed in a laminating device for laminating operations to make the semi-finished multi-layer boards into a multi-layer circuit board with an integrated structure.

[0003] In the lamination process, vacuuming plays a vital role. First of all, the role of the vacuum pump in the laminator is to remove the air between the materials and the gas released when heated, ensuring that the higher the vacuum degree, the cleaner the vacuum, and thus the higher the quality of the processed product. This continuous vacuuming process is crucial to maintaining a high vacuum degree, because fluctuations in vacuum degree will affect product quality.

[0004] During the lamination process, gas will be released continuously, so continuous vacuuming is required and the vacuum degree must be kept stable. This is because a stable vacuum degree helps maintain high product quality. Through effective vacuuming measures, excessive or insufficient resin flow can be avoided, thereby controlling the thickness uniformity of the press plate and improving production efficiency and product quality.

[0005] In the prior art, when hot pressing the multilayer board semi-finished products placed in the hot pressing chamber, it is necessary to evacuate the pressing cabinet before hot pressing to extract the air between the materials and the gases released when heated, so as to reduce the influence of the gases on the hot pressing of the multilayer board semi-finished products during the hot pressing process. However, during the vacuuming process before hot pressing, air flow and vibration of the pressing cabinet are easily generated in the hot pressing chamber, which is not conducive to maintaining the stability of the multilayer board semi-finished products. The multilayer board semi-finished products are prone to shifting during the vibration, affecting the accuracy of the hot pressing position in the later stage. Summary of the invention

[0006] The object of the present invention is to provide a lamination device for manufacturing a multi-layer circuit board to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A laminating device for manufacturing a multi-layer circuit board, comprising a laminating cabinet, a fixed hot pressing plate and a plurality of movable hot pressing plates, wherein the fixed hot pressing plate and the plurality of movable hot pressing plates are arranged longitudinally to form a plurality of hot pressing chambers, a vacuum pump suction machine, a power component for pushing the movable hot pressing plate for laminating, and further comprising:

[0008] A sealing door, wherein the sealing door is used to seal the opening of the pressing cabinet;

[0009] A sliding door assembly, the sliding door assembly is used to move the sealing door to achieve sealing of the opening of the pressing cabinet;

[0010] Two clamping assemblies, the two clamping assemblies are symmetrically arranged on both sides of the fixed hot pressing plate, and the clamping assemblies include a movable seat, a clamping claw assembly and a linear driving assembly for driving the movable seat to move;

[0011] Among them, after the multi-layer board semi-finished products are placed in multiple hot pressing chambers formed by a fixed hot pressing plate and multiple movable hot pressing plates, the sealing door is moved by the sliding door assembly to seal the opening of the pressing cabinet, and after sealing, the moving seat is driven to move by the linear drive assembly, and the clamping claw assembly is simultaneously driven to press and fix the movable hot pressing plate first, and then press the top of the multi-layer board semi-finished product to achieve the stabilization of the movable hot pressing plate and the multi-layer board semi-finished product, so as to prevent the airflow vibration formed by the subsequent vacuum extraction from affecting the stability of the multi-layer board semi-finished product.

[0012] It should be understood that in the prior art, when hot pressing the semi-finished multilayer board placed in the hot pressing chamber, it is necessary to evacuate the pressing cabinet before hot pressing to remove the air between the materials and the gas released when heated, so as to reduce the influence of the gas on the hot pressing of the semi-finished multilayer board during the hot pressing process. However, during the vacuuming process before hot pressing, air flow and vibration of the pressing cabinet are easily generated in the hot pressing chamber, which is not conducive to maintaining the stability of the semi-finished multilayer board. The semi-finished multilayer board is easily offset during vibration, which affects the accuracy of the hot pressing position in the later stage. The present technical solution can solve the above problems. The specific working principle is as follows:

[0013] First, the semi-finished multilayer board is placed on the top surface of a plurality of movable hot pressing plates, and then the sealing door is moved by the sliding door assembly to seal the opening of the pressing cabinet;

[0014] Then, the linear drive assembly drives the movable seat close to the movable hot press plate, and simultaneously drives the clamping claw assembly to press and fix the movable hot press plate first, and then press the top of the multi-layer board semi-finished product to achieve the stability of the movable hot press plate and the multi-layer board semi-finished product to prevent the air flow vibration formed by the subsequent vacuum extraction from affecting the stability of the multi-layer board semi-finished product.

[0015] Finally, the air in the pressing cabinet is extracted outwards through a vacuum pump suction machine to achieve vacuum treatment inside the pressing cabinet.

[0016] As an optional technical solution of the present invention, the sliding door assembly includes:

[0017] Two limit seats, the two limit seats are symmetrically fixedly connected to the two sides of the pressing cabinet, and the limit seats include a vertical slot and two guiding inclined slots;

[0018] Two guide pins arranged in sequence in the up-down direction, the two guide pins are slidably arranged on the inner wall of the guide chute, and are both fixedly connected to the side wall of the sealing door;

[0019] A traction assembly is used to pull the guide pin located above to indirectly pull the sealed door.

[0020] It should be understood that when the sealed door needs to be opened, the traction is released by the traction assembly, and the sealed door will drive the guide pin to move from the guide inclined groove to the vertical groove under the action of gravity until the guide pin located below falls to the bottom end of the vertical groove, and the sealed door is completely located below the opening of the pressing cabinet;

[0021] When the opening needs to be closed, the guide pin is pulled by the traction assembly, and the guide pin is pulled up in the vertical groove until the guide pin moves to the guide inclined groove. It will move under the limit of the guide inclined groove until the sealing door is completely close to the opening of the pressing cabinet to form a seal, thereby providing sealing conditions for the subsequent vacuum extraction.

[0022] As an optional technical solution of the present invention, the traction assembly includes:

[0023] Two traction shafts, the two traction shafts are rotatably connected to the top of the pressing cabinet, the ends of the traction shafts are fixedly mounted with traction rollers, the surfaces of the traction rollers are wrapped with traction belts, and the bottom ends of the traction belts are fixedly connected to the tops of the guide pins below;

[0024] A double-shaft motor is fixedly mounted on the top of the pressing cabinet, and two output shafts are respectively connected to two traction shafts to synchronously drive the two traction shafts to rotate.

[0025] It should be understood that by starting the dual-axis motor, the dual-axis motor can synchronously drive the two output shafts to rotate, the two output shafts synchronously drive the two traction shafts to rotate, the two traction shafts synchronously drive the traction rollers to rotate, the traction rollers unwind or reel the traction belt, thereby releasing or implementing traction on the guide pin.

[0026] As an optional technical solution of the present invention, the clamping jaw assembly includes:

[0027] A plurality of first mounting grooves are provided on the side wall of the movable seat, and the plurality of first mounting grooves correspond to the plurality of hot pressing chambers one by one;

[0028] A plurality of flip plates, wherein the plurality of flip plates are rotatably connected to the inner walls of the plurality of first mounting grooves respectively, a pressing plate is disposed at the end of the flip plate, and a height adjustment component is disposed at the top of the pressing plate;

[0029] A plurality of second mounting grooves are provided on the side wall of the movable seat, the plurality of second mounting grooves correspond to the plurality of hot pressing chambers one by one, a positioning claw is slidably installed in each of the plurality of second mounting grooves, a first supporting spring is fixedly connected between the positioning claw and the second mounting groove, and a top of the positioning claw is provided with a push-up inclined surface;

[0030] A rotation adjustment component is used to drive the multiple flip plates to flip synchronously.

[0031] It should be understood that in the clamping process, the flip plate is first flipped and adjusted by the rotating adjustment component so that the flip plate points to the movable hot pressing plate, and then the linear drive component is used to drive the movable seat to move, and the positioning claw is synchronously driven to move. In the process of the movement of the movable seat, the positioning claw first contacts the edge of the movable hot pressing plate, and while the movable hot pressing plate is squeezed and positioned, the positioning claw will rise until the entire positioning claw is in contact with the movable hot pressing plate. Under the reset pulling action of the first supporting spring, the positioning claw maintains a downward pressing trend. After the positioning claw is positioned, the pressing plate is adjusted by the height adjustment device to press the multi-layer board semi-finished product placed on the top of the movable hot pressing plate below, thereby first stabilizing the movable hot pressing plate, and then positioning the position of the multi-layer board semi-finished product on the movable hot pressing plate, thereby stabilizing the working station of the multi-layer board semi-finished product and preparing for the subsequent vacuum suction.

[0032] As an optional technical solution of the present invention, the height adjustment component includes

[0033] Two first traction plates, each of which has a first traction groove, wherein the first traction groove includes a first oblique groove and a first transverse groove;

[0034] A support frame, wherein the support frame slides through the flip plate and is fixedly connected to the top surface of the pressing plate, and a second support spring is connected between the support frame and the top surface of the flip plate;

[0035] A traction pin, two ends of the two traction pins are respectively slidably connected in the two first traction grooves, and the traction pins are arranged at the ends of the support frame;

[0036] An electric push rod, wherein the electric push rod is fixedly connected to the top of the flip plate, and a telescopic end thereof is fixedly connected to the two first traction plates.

[0037] It should be understood that when the positioning claw completes the positioning of the movable hot press plate, the electric push rod is started, and the electric push rod pulls the first traction plate. The first inclined groove on the first traction plate will act on the traction pin, causing the traction pin to move downward. The traction pin drives the support frame and the pressing plate to move downward synchronously until the multi-layer board semi-finished product is pressed.

[0038] As a further optimized technical solution of the present invention, the rotation adjustment component includes:

[0039] A driving motor is fixedly mounted on the top of the moving seat, and a supporting shaft is fixedly mounted on the output end of the driving motor. The supporting shaft passes through the moving seat and is fixedly connected to the ends of the flip plates of the first mounting slots.

[0040] It should be understood that during the hot pressing process, the hot pressing chamber will become smaller, and the flip plate must be away from the hot pressing chamber. When vacuuming before hot pressing, the semi-finished multilayer board needs to be positioned, and the flip plate will move into the hot pressing chamber. Therefore, by setting a rotary adjustment component, when vacuuming before hot pressing, the drive motor can be started, and the drive motor drives the support shaft to rotate, and the support shaft synchronously drives multiple flip plates to flip and point to the movable hot pressing plate, and move into the hot pressing chamber;

[0041] After the vacuuming is completed, the driving motor is started to drive the support shaft to rotate, driving the flip plate to reset and move away from the hot pressing chamber, thereby ensuring the smooth progress of the entire pressing process.

[0042] As a further optimized technical solution of the present invention, extension plates are slidably inserted at both ends of the pressing plate, and a movable adjustment component is provided on the top of the extension plate to adjust the two extension plates to extend out of the pressing plate before the pressing plate presses the semi-finished circuit board.

[0043] As a further optimized technical solution of the present invention, the mobile adjustment component includes:

[0044] Two first slide grooves, the two first slide grooves are symmetrically arranged on the top of the pressing plate;

[0045] Two second slide grooves, the two second slide grooves are symmetrically arranged on the top surface of the flip plate;

[0046] Two linkage rods, which are fixedly connected to the tops of the two extension plates and extend to the top of the flip plate after passing through the first slide slot and the second slide slot in sequence;

[0047] Two second traction plates, the two second traction plates are respectively slidably connected to the ends of the two first traction plates and are symmetrically arranged, the two second traction plates both have a second traction groove, and the second traction groove includes a second oblique groove and a second transverse groove;

[0048] Two adjusting pins are respectively fixedly connected to the tops of the two linkage rods and are respectively slidably arranged in the two second traction grooves.

[0049] It should be understood that during the clamping process, when the first traction plate moves, it will synchronously drive the second traction plate to move, and the second traction groove of the second traction plate will act on the adjusting pin. The adjusting pin will move under the action of the second inclined groove, and the adjusting pin will synchronously drive the linkage rod to move. The linkage rod will drive the extension plate to extend from the end of the pressing plate until the adjusting pin moves to the second transverse groove. The extension plate extends to its longest length, thereby extending the pressing plate, which is beneficial to increase the pressing area of ​​the pressing plate and further enhance the stability of the multi-layer board semi-finished product.

[0050] As an optional technical solution of the present invention, the power assembly is a lifting cylinder, the lifting cylinder is fixedly installed on the bottom surface of the cavity of the pressing cabinet, and a top pressure plate is fixedly installed on the output end.

[0051] It should be understood that when hot pressing is required, the lifting cylinder is started, and the lifting cylinder will push the fixed pressure plate upward to push the movable hot pressure plate, and the movable hot pressure plate will gradually approach and press until the top movable hot pressure plate is completely pressed against the fixed hot pressure plate.

[0052] As a further optimized technical solution of the present invention, the vacuum pump suction machine is fixedly installed on the back of the pressing cabinet, and the air suction port is connected to the interior of the pressing cabinet, and an air pressure sensor is fixedly installed on the inner wall of the pressing cabinet.

[0053] It should be understood that before hot pressing, after the multilayer board semi-finished products are loaded, vacuum is first performed until the air pressure sensor detects a certain air pressure value, and then the vacuum is stopped. Then, during the hot pressing process, the air pressure sensor detects that the air pressure value has risen, and the vacuum pump is started and pumped again until the supported air pressure value is maintained, and then the pumping is stopped. On the one hand, it reduces the loss of the vacuum pump, and on the other hand, it is conducive to maintaining the vacuum state.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. The linear drive assembly drives the movable seat close to the movable hot pressing plate, and synchronously drives the clamping claw assembly to press and fix the movable hot pressing plate first, and then press the top of the multi-layer board semi-finished product to achieve the stability of the movable hot pressing plate and the multi-layer board semi-finished product, so as to prevent the air flow vibration formed by the later vacuum from affecting the stability of the multi-layer board semi-finished product.

[0056] 2. The movable hot pressing plate is stabilized first, and then the position of the multi-layer board semi-finished product on the movable hot pressing plate is positioned, so that the position of the multi-layer board semi-finished product is stabilized, and preparations are made for the subsequent vacuum suction.

[0057] 3. During the clamping process, before the pressing plate is pressed, the extension plate is extended from the end of the pressing plate, which serves to extend the pressing plate, is beneficial to increase the pressing area of ​​the pressing plate, and further enhances the stability of the multilayer board semi-finished product.

DETAILED DESCRIPTION

[0071] See also Figure 1-Figure 11 The present invention provides a technical solution: a laminating device for manufacturing a multi-layer circuit board, comprising a laminating cabinet 1, a fixed hot pressing plate 2 and a plurality of movable hot pressing plates 3, wherein the fixed hot pressing plate 2 and the plurality of movable hot pressing plates 3 are arranged longitudinally to form a plurality of hot pressing chambers 6, a vacuum pump suction machine 7, and a power component for pushing the movable hot pressing plate 3 for laminating, and further comprising:

[0072] A sealing door 8, which is used to seal the opening of the pressing cabinet 1;

[0073] A sliding door assembly, which is used to move the sealing door 8 to seal the opening of the pressing cabinet 1;

[0074] Two clamping assemblies, the two clamping assemblies are symmetrically arranged on both sides of the fixed hot pressing plate 2, and the clamping assemblies include a movable seat 9, a clamping claw assembly and a linear driving assembly 10 for driving the movable seat 9 to move;

[0075] Specifically, the linear drive assembly 10 may be an electric cylinder.

[0076] Among them, after the multi-layer board semi-finished products are placed in multiple hot pressing chambers 6 formed by a fixed hot pressing plate 2 and multiple movable hot pressing plates 3, the sealing door 8 is moved by the sliding door assembly to seal the opening of the pressing cabinet 1, and after sealing, the moving seat 9 is driven to move by the linear drive assembly 10, and the clamping claw assembly is synchronously driven to press and fix the movable hot pressing plate 3 first, and then press the top of the multi-layer board semi-finished product to achieve the stability of the movable hot pressing plate 3 and the multi-layer board semi-finished product, so as to prevent the airflow vibration formed by the later vacuum extraction from affecting the stability of the multi-layer board semi-finished product.

[0077] Specifically, the pressing cabinet 1 has a pressing cavity 101, a fixed hot pressing plate 2 is fixedly installed on the inner top surface of the pressing cavity 101, a plurality of movable hot pressing plates 3 are linearly arrayed below the fixed hot pressing plate 2, and limiting columns 4 are movably inserted and penetrated between the four corners of the plurality of movable hot pressing plates 3, and the plurality of limiting columns 4 are fixedly connected to the inner bottom surface of the pressing cavity 101, and connecting belts 5 are connected between the two sides of the fixed hot pressing plate 2 and the side walls of the uppermost movable hot pressing plate 3, and adjacent movable hot pressing plates 3 are also connected by connecting belts 5, so that when the lifting pressure applied to the movable hot pressing plate 3 is cancelled, they are suspended and arranged in sequence under the action of gravity, and the hot pressing cavity 6 is opened to provide space for adding multilayer board semi-finished products.

[0078] It should be further explained that the side of the connecting belt 5 has a groove, which is used for bending the connecting belt 5 to the side away from the movable hot pressing plate 3 when the hot pressing chamber 6 is reduced, so as to avoid entering the hot pressing chamber 6.

[0079] It should be understood that in the prior art, when hot pressing the multilayer board semi-finished product placed in the hot pressing chamber 6, it is necessary to evacuate the pressing cabinet 1 before hot pressing to remove the air between the materials and the gas released when heated, so as to reduce the influence of the gas on the hot pressing of the multilayer board semi-finished product during the hot pressing process. However, during the vacuuming process before hot pressing, air flow and vibration of the pressing cabinet 1 are easily generated in the hot pressing chamber 6, which is not conducive to maintaining the stability of the multilayer board semi-finished product. The multilayer board semi-finished product is prone to deviation during vibration, which affects the accuracy of the hot pressing position in the later stage. This embodiment can solve the above problems. The specific working principle is as follows:

[0086] The traction assembly is used to pull the guide pin 12 located above, so as to indirectly pull the sealing door 8.

[0087] It should be understood that when the sealing door 8 needs to be opened, the traction is released by the traction assembly, and the sealing door 8 will drive the guide pin 12 to move from the guide inclined groove 1102 to the vertical groove 1101 under the action of gravity, until the guide pin 12 located below falls to the bottom end of the vertical groove 1101, and the sealing door 8 is completely located below the opening of the pressing cabinet 1;

[0088] When the opening needs to be closed, the guide pin 12 is pulled by the traction assembly, and the guide pin 12 is pulled to move upward in the vertical groove 1101 until the guide pin 12 moves to the guide inclined groove 1102. It will move under the limit of the guide inclined groove 1102 until the sealing door 8 is completely close to the opening of the pressing cabinet 1 to form a seal, thereby providing sealing conditions for the subsequent vacuum extraction.

Then, the linear drive component 10 drives the movable seat 9 to move, and synchronously drives the positioning claw 21 to move. During the movement of the movable seat 9, the positioning claw 21 first contacts the edge of the movable hot pressing plate 3. While squeezing and positioning the movable hot pressing plate 3, the positioning claw 21 will rise until the entire positioning claw 21 is in contact with the movable hot pressing plate 3. Under the reset pulling action of the first supporting spring 22, the positioning claw 21 maintains a downward pressing tendency force. After the positioning claw 21 is positioned, the pressing plate 19 is adjusted by the height adjustment device to press the multi-layer board semi-finished product placed on the top of the movable hot pressing plate 3 below, thereby first stabilizing the movable hot pressing plate 3, and then positioning the position of the multi-layer board semi-finished product on the movable hot pressing plate 3, thereby stabilizing the work station of the multi-layer board semi-finished product and preparing for the subsequent vacuum suction.

[0099] As an optional embodiment of the present invention, the height adjustment assembly includes

[0102] Traction pins 27, both ends of the two traction pins 27 are slidably connected in the two first traction grooves 24, and the traction pins 27 are arranged at the ends of the support frame 25;

[0103] The electric push rod 28 is fixedly connected to the top of the flip plate 18 , and the telescopic end of the electric push rod 28 is fixedly connected to the two first traction plates 23 .

[0104] It should be understood that when the positioning claw 21 completes the positioning of the movable hot press plate 3, the electric push rod 28 is started, and the electric push rod 28 pulls the first traction plate 23. The first inclined groove 2401 on the first traction plate 23 will act on the traction pin 27, causing the traction pin 27 to move downward. The traction pin 27 drives the support frame 25 and the pressing plate 19 to move downward synchronously until the multilayer board semi-finished product is pressed.

The support shaft 30 passes through the moving seat 9 and is fixedly connected to the ends of the flip plates 18 of the multiple first mounting grooves 17 .

[0107] It should be understood that during the hot pressing process, the hot pressing chamber 6 will become smaller, and the flip plate 18 must be away from the hot pressing chamber 6. When vacuuming before hot pressing, the semi-finished multilayer board needs to be positioned, and the flip plate 18 will move into the hot pressing chamber 6. Therefore, by setting a rotary adjustment component, when vacuuming before hot pressing, the drive motor 29 can be started, and the drive motor 29 drives the support shaft 30 to rotate, and the support shaft 30 synchronously drives the multiple flip plates 18 to flip and point to the movable hot pressing plate 3, and move into the hot pressing chamber 6;

[0108] After the vacuuming is completed, the driving motor 29 is started again to drive the supporting shaft 30 to rotate, thereby driving the flip plate 18 to reset and move away from the hot pressing chamber 6, thereby ensuring the smooth progress of the entire pressing process.

[0109] As a further optimized embodiment of the present invention, extension plates 31 are slidably inserted at both ends of the pressing plate 19, and a movable adjustment component is provided on the top of the extension plate 31 for adjusting the two extension plates 31 to extend out of the pressing plate 19 before the pressing plate 19 presses the semi-finished circuit board.

[0110] As a further optimized embodiment of the present invention, the mobile adjustment component includes:

[0111] Two first slide grooves 32, the two first slide grooves 32 are symmetrically opened on the top of the pressing plate 19;

[0112] Two second slide grooves 33, the two second slide grooves 33 are symmetrically opened on the top surface of the flip plate 18;

[0113] Two linkage rods 34, which are fixedly connected to the tops of the two extension plates 31, and sequentially pass through the first slide slot 32 and the second slide slot 33 and then extend to the top of the flip plate 18;

[0114] Two second traction plates 35, the two second traction plates 35 are respectively slidably connected to the ends of the two first traction plates 23 and are symmetrically arranged, the two second traction plates 35 each have a second traction groove 36, and the second traction groove 36 includes a second oblique groove 3601 and a second transverse groove 3602;

[0115] Two adjusting pins 37 are respectively fixedly connected to the tops of the two linkage rods 34 and are respectively slidably disposed in the two second traction grooves 36 .

[0116] It should be understood that during the clamping process, when the first traction plate 23 moves, it will synchronously drive the second traction plate 35 to move, and the second traction groove 36 of the second traction plate 35 will act on the adjusting pin 37. The adjusting pin 37 will move under the action of the second inclined groove 3601, and the adjusting pin 37 will synchronously drive the linkage rod 34 to move. The linkage rod 34 will drive the extension plate 31 to extend from the end of the pressing plate 19 until the adjusting pin 37 moves to the second transverse groove 3602. The extension plate 31 extends to its longest length, thereby extending the pressing plate 19, which is beneficial to increase the pressing area of ​​the pressing plate 19 and further enhance the stability of the multi-layer board semi-finished product.

[0117] As an optional embodiment of the present invention, the power component is a lifting cylinder 38, which is fixedly installed on the bottom surface of the cavity of the pressing cabinet 1, and a pressing plate 39 is fixedly installed on the output end.

[0118] It should be understood that when hot pressing is required, the lifting cylinder 38 is started, and the lifting cylinder 38 will push the fixed pressure plate to push the movable hot pressing plate 3 upward, and the movable hot pressing plate 3 will gradually approach and press until the top movable hot pressing plate 3 is completely pressed against the fixed hot pressing plate 2.

[0119] As a further optimized embodiment of the present invention, the vacuum pump suction machine 7 is fixedly installed on the back of the pressing cabinet 1, and the air suction port is connected to the interior of the pressing cabinet 1, and an air pressure sensor 40 is fixedly installed on the inner wall of the pressing cabinet 1.

[0120] It should be understood that before hot pressing, after the multilayer board semi-finished products are loaded, vacuum is first performed until the air pressure sensor 40 detects a certain air pressure value, and then the vacuum is stopped. Then, during the hot pressing process, the air pressure sensor 40 detects that the air pressure value has risen, and the vacuum pumping machine 7 is started to pump again until the supported air pressure value is maintained, and then the pumping is stopped. On the one hand, it reduces the loss of the vacuum pumping machine 7, and on the other hand, it is conducive to maintaining the vacuum state.
