[0002] With the rapid development of the electronic industry, the demand for copper-clad plates, printed circuit boards, and insulating plates, etc. electronic base materials is increasing. The performance of vacuum laminators, as key equipment for producing these materials, directly affects the quality and production efficiency of products. The existing vacuum laminators mainly consist of a rack, a hot plate, an oil cylinder, a control system, and other core components. The working process is as follows: the loading and unloading machine pushes the materials to be pressed to the hot plate of the press, the door is closed, and the pressing program is started. The plunger moves upward to push the hot plate to close layer by layer, and the pressing is carried out according to the process requirements under the adjustment of the control system.

[0003] At present, common vacuum laminators generally have 6-24 openings, the working temperature range is 160-220℃, the system pressure can reach 12-22MPa, and the product surface pressure is maintained at 8-12MPa. In actual production process, the hot plate is the core component to ensure product quality, and the temperature uniformity and stability of the hot plate directly affect the performance of the product. However, in the prior art, the temperature difference between the uppermost hot plate and the lowermost hot plate is large due to the high working temperature of the hot plate, which leads to unstable product quality. SUMMARY

[0004] The present application aims to at least solve one of the above technical problems in the prior art to some extent. To this end, the present application provides a vacuum laminator to ensure that the top hot plate and the bottom hot plate are uniform with other hot plates, and to achieve uniform pressing product thickness and surface pressure.

[0005] A vacuum laminator heat insulation plate, comprising

[0006] an asbestos plate;

[0007] a polyimide plate, which is connected to the asbestos plate;

[0008] a compensation plate, which is arranged between the asbestos plate and the polyimide plate.

[0009] In optional or preferred embodiments, the compensation plate is an iron foil or a copper foil.

[0010] In optional or preferred embodiments, the thickness of the polyimide plate is 20mm, and the thickness of the asbestos plate is 10mm.

[0011] A vacuum press machine characterized in comprising the heat insulation plate of any one of the above-mentioned vacuum press machine, the vacuum press machine heat insulation plate is arranged between the cushion block at the top and the heat plate at the top and between the cushion block at the bottom and the heat plate at the bottom.

[0012] In the optional or preferred embodiment, the polyimide plate is adjacent to the heat plate, and the asbestos plate is adjacent to the cushion block.

[0013] Based on the above technical solution, the application has at least the following beneficial effects: the asbestos plate can block the heat conduction to the top cushion block and the bottom cushion block, reduce the heat loss, and also ensure that the temperature of the top heat plate and the bottom heat plate is uniform with that on other heat plates. In addition, the asbestos plate at the bottom cushion block also blocks the heat conduction to the plunger, effectively ensuring the working temperature of the hydraulic oil.

[0014] Due to the design, processing, installation and other errors of the press machine heat plate, in order to eliminate the error, after the press is installed, the compensation plate between the asbestos plate and the polyimide plate can eliminate the accumulated error between the heat plates, and realize the uniformity of the thickness and surface pressure of the pressed product.

[0015] In the application, the polyimide plate has high hardness, and after high-pressure pressing of the product, the compensation plate will not be embedded into the surface of the polyimide plate, and the thickness adjustment amount will not change, so long-term production does not need to adjust the press again, and the production efficiency will not be affected.

[0020] The embodiments of the application will be further described in detail below in combination with the drawings and embodiments. The following embodiments are used to illustrate the application, but cannot be used to limit the scope of the application.

[0021] In the description of the embodiments of the present application, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0023] In the embodiments of the present application, unless otherwise expressly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0024] With the rapid development of the electronics industry, the demand for basic electronic materials such as copper-clad laminates, printed circuit boards, and insulating boards continues to increase. As key equipment for producing these materials, the performance of vacuum pressing units directly impacts product quality and production efficiency. Existing vacuum pressing units primarily consist of core components such as a frame, hot plate, oil cylinder, and control system. Their operation is as follows: a loader pushes the material to be pressed onto the hot plate of the press. After the door closes, the pressing process begins. The plunger moves upward, pushing the hot plate closed layer by layer. Pressing is performed according to process requirements under the control of the control system.

[0025] Currently, common vacuum laminating machines typically have 6 to 24 openings, an operating temperature range of 160 to 220°C, a system pressure of 12 to 22 MPa, and a product surface pressure maintained at 8 to 12 MPa. In actual production, the hot plate is a core component for ensuring product quality, and its temperature uniformity and stability directly impact product performance. However, due to the high operating temperature of the hot plates in existing technologies, the heat loss between the top and bottom hot plates is significant. This temperature difference can lead to unstable product quality.

[0026] Reference Figure 1 The present application provides a vacuum laminating machine heat insulation board 100 , comprising an asbestos board 120 , a polyimide board 110 and a compensation board 130 .

[0027] The polyimide plate 110 and the asbestos plate 120 are bonded to each other, and the compensation plate 130 is disposed between the asbestos plate 120 and the polyimide plate 110 .

[0028] The asbestos sheet 120 blocks heat conduction to the top pad 200 and bottom pad 300, reducing heat loss and ensuring that the top heating plate 400 and bottom heating plate 500 maintain a uniform temperature with the other heating plates. Furthermore, the asbestos sheet 120 at the bottom pad 300 also blocks heat conduction to the plunger, effectively maintaining the operating temperature of the hydraulic oil.

[0029] Since there are errors in the design, processing, and installation of the hot plates of the pressing machine, in order to eliminate these errors, after the press is installed, the compensation plate 130 between the asbestos board 120 and the polyimide board 110 can eliminate the accumulated errors between the hot plates and achieve uniform thickness and surface pressure of the pressed product.

[0030] In this application, the polyimide plate 110 has a relatively high hardness. After the product is pressed under high pressure, the compensation plate 130 will not be embedded in the surface of the polyimide plate 110, and the thickness adjustment amount will not change. Therefore, there is no need to adjust the press during long-term production, which will not affect production efficiency.

[0031] In some embodiments, the compensation plate 130 is an iron foil or a copper foil.

[0032] In some embodiments, the thickness of the polyimide board 110 is 20 mm, and the thickness of the asbestos board 120 is 10 mm.

[0033] Reference Figure 2The present application also provides a vacuum laminating machine, comprising any one of the above-mentioned vacuum laminating machine heat insulation plates 100, wherein the vacuum laminating machine heat insulation plates 100 are provided between the top pad 200 and the top hot plate 400, and between the bottom pad 300 and the bottom hot plate 500. This vacuum laminating machine can block heat conduction to the top pad 200 and the bottom pad 300 through the asbestos board 120, thereby reducing heat loss and ensuring that the temperature of the top hot plate 400 and the bottom hot plate 500 are consistent with that of other hot plates. The polyimide plate 110 has a high hardness. During the pressing process, the compensation plate 130 will not be embedded in the surface of the polyimide plate 110, and the thickness adjustment amount will not change. Therefore, there is no need to adjust the press during long-term production, which will not affect production efficiency.

[0034] In some embodiments, the polyimide sheet 110 is adjacent to the heat plate, and the rockwool sheet 120 is adjacent to the spacer.

[0035] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.
