As the electronics industry continues to increase its requirements for circuit board performance, the operating temperature of hot pressing equipment has also increased significantly.

[0003] Currently, hot pressing equipment mainly relies on a single insulation material to reduce heat loss. While insulation materials can reduce heat conduction to some extent, their effect on blocking heat radiation is limited. A large amount of heat is dissipated outward through heat radiation, resulting in significant heat loss. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the main objective of this application is to provide a hot press plate module and a hot press device.

[0005] To achieve the above objectives, this application adopts the following technical solution.

[0006] According to a first aspect of the present application, a hot press plate module is provided, including a hot press plate and a heat insulation component. The hot press plate has two hot press surfaces disposed opposite to each other, and a sidewall connected to the edges of the two hot press surfaces. The heat insulation component includes a heat reflector plate and a locking member. The heat reflector plate and the sidewall are disposed opposite to each other, and the locking member passes through the heat reflector plate and is connected to the sidewall. The heat reflector plate has a heat reflective surface disposed opposite to the sidewall, and the heat reflective surface is recessed in the direction away from the sidewall.

[0007] The first possibility is that the heat reflector and the heat press plate are set apart.

[0008] The second possibility is that the heat reflective surface is a cylindrical arc surface; wherein the axis of the heat reflective surface is located inside the side wall or the hot press plate; and / or, the central angle of the heat reflective surface is ≤180 degrees.

[0009] The third possibility is that the heat reflector includes a main body and a reflective layer, with the main body and sidewalls disposed opposite to each other; the reflective layer covers at least the surfaces of the main body and sidewalls opposite to each other, and the reflective layer has a heat reflective surface; a locking member passes through at least the main body to fix the heat reflector to the sidewalls.

[0010] The fourth possibility is that the heat insulation assembly also includes a heat insulation plate, which is arranged opposite to a heat reflector, with the heat reflector located between the sidewall and the heat insulation plate; a locking element is inserted through the heat insulation plate.

[0011] The fifth possibility is that the heat insulation panel and the heat reflector panel are arranged alternately.

[0012] The sixth possibility is that the heat reflector has a heat-emitting surface that is positioned opposite to the heat insulation plate, and the heat-emitting surface protrudes from the heat insulation plate.

[0013] The seventh possibility is that the heat insulation assembly further includes a first heat insulation gasket, which is sleeved on the locking member and disposed between the heat reflector and the sidewall; and / or, the heat insulation assembly further includes a second heat insulation gasket, which is sleeved on the locking member and disposed between the heat reflector and the heat insulation plate; and / or, the heat insulation assembly further includes a third heat insulation gasket, which is sleeved on the locking member and disposed on the side of the heat insulation plate facing away from the heat reflector.

[0014] The eighth possibility is that the hot press plate includes multiple sidewalls, each distributed circumferentially along the hot press surface; each sidewall corresponds to at least one thermal insulation component.

[0015] According to a second aspect of the embodiments of this application, a hot pressing device is provided, including a body and a hot pressing plate module in any of the above embodiments, the body being provided with a hot pressing cavity, and the hot pressing plate module being disposed in the hot pressing cavity.

[0016] The hot press plate module according to the embodiments of this application has at least the following beneficial effects: By setting the heat reflector and the sidewall to be opposite each other, and the locking member passing through the heat reflector and connected to the sidewall, the heat reflector can be fixed to the hot press plate, making installation convenient and the connection reliable. By setting the heat reflective surface of the heat reflector to be opposite to the sidewall of the hot press plate, and the heat reflective surface is recessed in the direction away from the sidewall, the recessed heat reflective surface can better reflect the heat radiated from the sidewall back to the hot press plate, which helps to reduce the outward dissipation of heat in the form of thermal radiation, reducing heat loss. When the hot press plate module is applied to hot pressing equipment, it can also reduce the ambient temperature of the factory, eliminating or reducing the need for additional cooling equipment and reducing energy consumption.

[0023] Combination Figures 1 to 2 A hot pressing device 10 according to an embodiment of this application includes a body 200 and a hot pressing plate module 100.

[0024] The machine body 200 is provided with a hot pressing chamber 210, and the hot pressing plate module 100 is located in the hot pressing chamber 210. The hot pressing plate module 100 can be used to hot press circuit board materials. The circuit board can also be called PCB (Printed Circuit Board), printed circuit board, printed circuit board, circuit board, etc.

[0025] As an example, the hot pressing device 10 may include a lifting platform 300 and a drive unit 400. The lifting platform 300 is vertically movable within the body 200, and a hot pressing chamber 210 may be formed between the lifting platform 300 and the inner top wall of the body 200. A vertically extending guide rail may be provided within the hot pressing chamber 210, and a hot pressing plate module 100 is movably connected to the guide rail. The drive unit 400 is used to drive the lifting platform 300 to move up and down. There may be multiple hot pressing plate modules 100, which may be vertically spaced between the lifting platform 300 and the inner top wall of the hot pressing chamber 210. A pressing space is formed between any two adjacent hot pressing plate modules 100, and this pressing space can be used to place circuit board materials. When the hot press equipment 10 is working, the lifting platform 300 moves upward under the drive of the drive component 400, causing the hot press plate modules 100 to move closer to each other to press multiple circuit board materials together, which helps to improve the working efficiency of the hot press equipment 10. The hot press plate module 100 can adopt oil heating, built-in heater heating or other heating methods, and specific methods can be referred to the prior art. This application does not limit it.

[0026] It should be noted that the hot pressing device 10 may also include a vacuum pump, which can be connected to the body 200 to extract air from the hot pressing chamber 210, thereby switching the hot pressing chamber 210 to a vacuum state. When the hot pressing device 10 is working, the hot pressing chamber 210 can be in a vacuum state. In a vacuum state, there is no air in the hot pressing chamber 210, and heat can only be transferred through heat conduction and heat radiation, but not through heat convection, which can reduce the heat loss of the hot pressing plate module 100.

[0027] Combination Figures 3 to 5 It is understood that the hot press plate module 100 includes a hot press plate 110 and a heat insulation component 130, and the heat insulation component 130 includes a heat reflector plate 131 and a locking member 133.

[0028] The hot press plate 110 has two hot press surfaces 111 arranged opposite to each other, and a side wall 113 connected to the edges of the two hot press surfaces 111. The hot press surfaces 111 can be used to press circuit board materials.

[0029] As an example, the hot press plate 110 is generally rectangular in shape and has two hot pressing surfaces 111 arranged opposite to each other along its thickness direction. The hot pressing surfaces 111 are used to press circuit board materials together. When the hot press plate 110 is applied to a hot pressing device 10 (such as…),… Figure 2 In the case shown, the thickness direction of the hot press plate 110 is approximately vertical, and the side wall 113 of the hot press plate 110 is approximately located on one side of the hot press plate 110 along the horizontal direction.

[0030] The heat reflector 131 and the side wall 113 are arranged opposite to each other, and the locking member 133 passes through the heat reflector 131 and is connected to the side wall 113 (e.g. Figure 4 and Figure 6 As shown, the heat reflector 131 is fixed to the heat press plate 110, which is convenient to install and has a reliable connection.

[0031] As an example, the locking member 133 may include a connected head and a rod, the diameter of which may be larger than the diameter of the rod, and the rod may be a threaded rod. The heat reflector 131 may have a first hole, and the side wall 113 may have a second hole. The first and second holes are opposite each other and are both threaded holes. The rod may be threaded into the first and second holes, and the head may be located on the side of the heat reflector 131 facing away from the side wall 113, thereby fixing the heat reflector 131 to the side wall 113. Understandably, the first hole may also be a non-threaded hole, and the rod and the first hole may be connected and fixed by interference fit or other means.

[0032] The number of locking elements 133 can be one or more, and "more" can refer to two or more. The specific number can be flexibly set according to the requirements so that the heat reflector 131 can be stably fixed to the side wall 113.

[0033] The heat reflector plate 131 is provided with a heat reflective surface 1311 disposed opposite to the side wall 113. The heat reflective surface 1311 is recessed in the direction away from the side wall 113. In this way, the recessed heat reflective surface 1311 can better reflect the heat radiated from the side wall 113 back to the hot press plate 110, which helps to reduce the heat loss in the form of heat radiation and reduce heat loss. When the hot press plate module 100 is applied to the hot press equipment 10, it can also reduce the ambient temperature of the factory, eliminating the need for or reducing the need for additional cooling equipment and reducing energy consumption.

[0034] The recessed heat reflective surface 1311 can refer to an arc surface that is recessed in the direction away from the sidewall 113. For example, the heat reflective surface 1311 can be a circular arc surface, an elliptical arc surface, a sphere, or other shapes. The heat reflective surface 1311 can be a smooth arc surface or an arc surface composed of multiple planes.

[0035] The heat reflector 131 can be made of aluminum plate or other reflective material, and the heat reflector surface 1311 can be set as a glossy surface to improve the reflection efficiency.

[0036] It is understandable that the heat reflector 131 and the heat press plate 110 can be spaced apart, thereby avoiding direct contact between the heat reflector 131 and the heat press plate 110 for heat conduction. The heat press plate 110 and the heat reflector 131 only contact each other through the locking member 133. That is, the heat conduction between the heat press plate 110 and the heat reflector 131 is only through the locking member 133, which reduces the contact area and can improve the situation where the heat of the heat press plate 110 is transferred to the heat reflector 131 by heat conduction, further reducing the situation where heat dissipates outward.

[0037] It is understood that the heat reflective surface 1311 is a cylindrical arc surface with its axis located inside the side wall 113 or the hot press plate 110. Thus, the heat reflective surface 1311 can reflect heat to the hot press plate 110, so that the heat dissipated laterally from the hot press plate 110 can be used to act back on the hot press plate 110, further reducing heat loss.

[0038] The extension direction of the heat reflective surface 1311 can be parallel or approximately parallel to the extension direction of the sidewall 113.

[0039] Understandably, the central angle of the heat reflector 1311 is ≤180 degrees, which helps to avoid the problem of excessive bending of the heat reflector 1311 causing some heat to be reflected to the non-heat plate 110 area. This allows the reflected heat to be concentrated on the heat plate 110, reducing ineffective reflection.

[0040] As an example, the central angle of the heat reflective surface 1311 can be 180 degrees, 172 degrees, 130 degrees, 128 degrees, 100 degrees, 95 degrees, 82 degrees or other angles, which can be flexibly set according to the requirements.

[0041] It should be noted that the heat reflective surface 1311 may have two oppositely arranged edges, each edge being flush or approximately flush with one of the hot pressing surfaces 111, which helps the heat reflective surface 1311 to more comprehensively reflect the heat radiated from the side wall 113 back to the hot pressing plate 110.

[0042] It is understood that the heat reflector 131 may include a main body and a reflective layer.

[0043] The main body and sidewall 113 can be arranged opposite each other, and the reflective layer covers at least the opposite surfaces of the main body and sidewall 113. The reflective layer can be provided with a heat-reflective surface 1311, so that the heat reflective plate 131 can be divided into two parts: the main body and the reflective layer. The materials of the main body and the reflective layer can be designed separately. The reflective layer can be made of a material with high reflectivity, while the material of the main body can be made of ordinary heat-insulating material, which helps to improve the reflectivity while reducing the manufacturing cost of the heat reflective plate 131.

[0044] The reflective layer can be a coating or a sheet. When the reflective layer is a coating, the reflective paint can be applied to the surface of the main body and solidify to form the reflective layer. When the reflective layer is a sheet, it can be fixed to the main body by welding, snap-fitting, fasteners, or other methods.

[0045] The reflective layer can be made of aluminum, gold, or other materials that reflect heat. The material of the main body can be flexibly set according to requirements, and this embodiment does not impose any restrictions.

[0046] The locking member 133 is at least inserted through the main body to fix the heat reflector 131 to the side wall 113.

[0047] As an example, the first hole in the above example can be located in the main body.

[0048] It should be noted that the locking element 133 may or may not be inserted into the reflective layer; the specific configuration can be flexibly determined according to the requirements.

[0049] It is understood that the insulation component 130 may also include an insulation panel 135.

[0050] The heat insulation plate 135 and the heat reflector plate 131 can be arranged opposite to each other. The heat reflector plate 131 can be located between the side wall 113 and the heat insulation plate 135, thereby forming a double heat insulation structure of the heat reflector plate 131 and the heat insulation plate 135. The heat reflector plate 131 is mainly used to reflect heat, and the heat insulation plate 135 can further block the heat radiated from one side of the heat reflector plate 131, which helps to further cut off the path of heat transfer to the outside.

[0051] The heat radiated from one side of the heat reflector 131 may include the heat radiated from the heat reflector 131 itself, as well as some of the heat radiated from the heat plate 110 but not reflected by the heat reflector 1311 and thus escaped.

[0052] The locking member 133 can be inserted into the heat insulation plate 135, thereby enabling the heat insulation plate 135, the heat reflector plate 131 and the hot press plate 110 to be fixed simultaneously. This helps to make the overall structure of the hot press plate module 100 more stable and avoids the need for additional connection structures to increase the heat conduction area, further reducing heat loss.

[0053] It should be noted that most of the heat radiated from the hot press plate 110 is reflected back to the hot press plate 110 by the heat reflector surface 1311, and less heat is transferred to the heat insulation plate 135. Therefore, materials with lower heat insulation effect can be selected, the range of materials for the heat insulation plate 135 is wider, and the manufacturing cost of the heat insulation plate 135 can be reduced. For example, the heat insulation plate 135 can be made of modified glass fiber composite material board, microporous heat insulation material board or other heat insulation materials.

[0054] It is understandable that the heat insulation plate 135 and the heat reflector plate 131 can be spaced apart, thereby avoiding direct contact between the heat insulation plate 135 and the heat reflector plate 131 for heat conduction. The heat insulation plate 135 and the heat reflector plate 131 are only in contact through the locking member 133. That is, the heat conduction between the heat insulation plate 135 and the heat reflector plate 131 is only through the locking member 133, which can improve the situation where the heat of the heat reflector plate 131 is transferred to the heat insulation plate 135 by heat conduction, and further reduce the situation where heat is dissipated to the outside.

[0055] It is understood that the heat reflector 131 may have a heat emitting surface 1313 disposed opposite to the heat insulation plate 135. The heat emitting surface 1313 protrudes towards the heat insulation plate 135. In this way, the protruding heat emitting surface 1313 can change the direction of heat radiation, which helps to radiate heat more dispersedly. This reduces the situation where heat is concentrated and radiated to the heat insulation plate 135, causing the heat insulation plate 135 to overheat. This further reduces the temperature of the heat insulation plate 135, thereby allowing the selection of materials with lower heat insulation effect. The range of materials to be selected for the heat insulation plate 135 is further expanded, which can further reduce the manufacturing cost of the heat insulation plate 135.

[0056] The shape of the heat-emitting surface 1313 is roughly the same as that of the heat-reflecting surface 1311, the only difference being that the heat-reflecting surface 1311 is concave while the heat-emitting surface 1313 is convex, which will not be elaborated further.

[0057] It is understood that the thermal insulation component 130 may also include a first thermal insulation gasket 137 (such as...). Figure 4 As shown, the first heat insulation pad 137 is sleeved on the locking member 133 and disposed between the heat reflector 131 and the side wall 113. In this way, the first heat insulation pad 137 can separate the heat reflector 131 and the side wall 113, so that a gap can be maintained between the heat reflector 131 and the side wall 113. This helps to prevent the heat reflector 131 and the side wall 113 from directly contacting each other and providing a heat conduction channel. The first heat insulation pad 137 can also block the heat radiated outward from the peripheral wall of the locking member 133.

[0058] As an example, the first heat-insulating pad 137 may abut against the heat reflector 131 and the sidewall 113.

[0059] It is understood that the thermal insulation component 130 may also include a second thermal insulation pad 139 (such as...). Figure 4 As shown, the second heat insulation gasket 139 is sleeved on the locking member 133 and positioned between the heat reflector 131 and the heat insulation plate 135. In this way, the second heat insulation gasket 139 can separate the heat reflector 131 and the heat insulation plate 135, so that a gap can be maintained between the heat reflector 131 and the heat insulation plate 135. This helps to prevent the heat reflector 131 and the heat insulation plate 135 from directly contacting each other and providing a heat conduction channel. The second heat insulation gasket 139 can also block the heat radiated outward from the peripheral wall of the locking member 133.

[0060] As an example, a second heat-insulating pad 139 may be placed between the heat reflector 131 and the heat-insulating plate 135.

[0061] It is understood that the thermal insulation component 130 may also include a third thermal insulation pad 141 (such as...). Figure 4 and Figure 6 As shown, the third heat insulation pad 141 is sleeved on the locking member 133 and disposed on the side of the heat insulation plate 135 facing away from the heat reflector plate 131. In this way, the third heat insulation pad 141 can separate the head of the locking member 133 from the heat insulation plate 135, so that a gap can be maintained between the head and the heat insulation plate 135. This helps to prevent the head and the heat insulation plate 135 from directly contacting each other and providing a heat conduction channel. The third heat insulation pad 141 can also block the heat radiated outward from the peripheral wall of the locking member 133.

[0062] As an example, the third heat insulation pad 141 may abut against the head of the locking member 133 and the heat insulation plate 135.

[0063] The first heat insulation pad 137, the second heat insulation pad 139, and the third heat insulation pad 141 can be made of the same material as the heat insulation board 135, or they can be made of other heat insulation materials.

[0064] It is understood that the hot press plate 110 may include multiple sidewalls 113, each sidewall 113 may be distributed circumferentially along the hot press surface 111, each sidewall 113 may correspond to at least one heat insulation component 130, so that each heat insulation component 130 can generally form an annular frame structure, and each heat insulation component 130 can block the radiation of heat from the periphery of the hot press plate 110, so as to trap the heat in the inner ring side of the annular frame, which helps to better reduce heat loss.

[0065] In the hot press plate module 100 and hot press equipment 10 provided in this application embodiment, by setting the heat reflector plate 131 and the side wall 113 to be opposite each other, and the locking member 133 passing through the heat reflector plate 131 and connected to the side wall 113, the heat reflector plate 131 can be fixed to the hot press plate 110. The installation method is convenient and the connection is reliable. By setting the heat reflective surface 1311 of the heat reflector plate 131 to be opposite to the side wall 113 of the hot press plate 110, and the heat reflective surface 1311 is recessed in the direction away from the side wall 113, the recessed heat reflective surface 1311 can better reflect the heat radiated from the side wall 113 back to the hot press plate 110, which helps to reduce the loss of heat in the form of heat radiation, reduce heat loss. When the hot press plate module 100 is applied to the hot press equipment 10, it can also reduce the ambient temperature of the factory, eliminating the need for or reducing the need for additional cooling equipment, and reducing energy consumption.

[0066] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
