[0001] Cross-references of prior documents This application claims priority to Chinese application No. CN2024115488488, filed on November 1, 2024, entitled "Heat Transfer Method, Components, Hot Press and System", and Chinese application No. CN2025111125314, filed on August 8, 2025, entitled "Heater, Kit, Apparatus, Hot Press, Automatic Hot Press, System and Method", the contents of which are considered part of the disclosure of this application and are incorporated herein by reference in their entirety. Technical Field

[0002] This utility model relates to the field of heat transfer technology, specifically to a heat transfer heater and a hot press. Background Technology

[0003] Existing flexible heaters used for heat transfer printing on cylindrical substrates such as cups generally include a flexible heating layer, a flexible substrate, and a thin-walled metal shell bonded together sequentially from the inside out. The heater as a whole has a cylindrical curved structure, and its interior is enclosed to form a heat-pressing channel defined by the inner flexible heating layer on the side walls. During operation, the substrate loaded with the transfer material is placed in the heat-pressing channel, and the elements of the transfer material are thermally transferred to the substrate using the heat generated by the flexible heating layer. The flexible substrate of this type of flexible heater is usually made of foamed silicone. Due to the material properties of the foamed silicone itself, the bending range of the flexible heater is limited, resulting in the inability to join the two ends of the flexible heater when bending to form the heat-pressing channel, and forming a large opening. As a result, this type of flexible heater cannot completely adhere to the part of the substrate corresponding to the above-mentioned opening for heat pressing. Utility Model Content

[0004] The purpose of this patent is to overcome the inability of existing flexible heaters to heat-press the corresponding opening of the substrate, and to provide a heat transfer heater and a heat press that solves the defect that the opening position of the flexible heater cannot heat-press the substrate by setting an edge pressing part.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The heat transfer heater provided in this application includes two or more rigid substrates. Two adjacent substrates are movably coupled. Two substrates located on the side are arranged apart and not connected. The free side of each substrate is constructed with a mounting connection portion extending axially to both ends of the corresponding substrate. The inner wall of the mounting connection portion extends at least partially axially to form an edge pressing portion that is continuous with the inner side of the corresponding substrate. The two or more rigid substrates and the edge pressing portion enclose each other to form a hot pressing channel. The free side of the substrate is constructed such that the inner diameter of the hot pressing channel can be adjusted by relative driving.

[0006] The edge pressing part of this method can be set in the following two ways: 1. The edge pressing part is arranged axially on part of the inner wall of the mounting connection part. This method can form a clearance space between the inner walls of the mounting connection parts on both sides outside the edge pressing part. This clearance space can be used for protruding structures on the surface of the substrate, such as for heat transfer printing on cups with handles.

[0007] 2. The edge pressing part extends axially to both ends of the mounting connection part. The edge pressing part of this type of setting is axially distributed throughout the inner wall of the mounting connection part, which is suitable for substrates with flat surfaces and no protruding structures.

[0008] Furthermore, the inner walls of the mounting connection parts on the free sides of the two substrates are constructed as relatively parallel planes, which can avoid interference between the two mounting connection parts.

[0009] Another aspect of this application provides a hot press, which includes a frame, a heating device, and a drive device. The frame is configured with a heating device mounting area. The heating device includes the aforementioned heat transfer heater, which is mounted in the heating device mounting area. The mounting connection of one side of the substrate is directly or indirectly fixedly connected to the first side of the heating device mounting area. The drive device is configured on the second side of the heating device mounting area and is used to control the movement of another substrate located on the side, thereby realizing the opening or closing of the hot pressing channel.

[0010] Furthermore, each mounting connection is connected to a first guide rail, and the first and second sides of the heating device mounting area are equipped with second guide rails. The first guide rail and the second guide rail slide together. This arrangement facilitates the connection and disassembly of the heat transfer heater and the frame.

[0011] Another aspect of this application provides a heat transfer heater comprising two or more rigid substrates, two adjacent substrates being movably coupled, and two substrates located on the side being spaced apart and not connected. The free side of the substrate is at least partially constructed with an edge pressing portion along the axial direction. The edge pressing portion extends out of the inner wall of the corresponding substrate and is continuous with the inner side of the substrate. The two or more rigid substrates and the edge pressing portion enclose each other to form a heat pressing channel. The free side of the substrate is configured such that the inner diameter of the heat pressing channel can be adjusted by relative driving.

[0012] The edge pressing part of this method can be set in the following two ways: 1. The edge pressing part is arranged axially on the inner wall of the corresponding substrate. This method can form a clearance space between the inner walls of the substrate on both sides, outside the edge pressing part. This clearance space can be used for protruding structures on the surface of the substrate, such as for heat transfer printing on cups with handles.

[0013] 2. The edge pressing part extends axially to both ends of the corresponding substrate. The edge pressing part of this setting is axially distributed throughout the inner wall of the corresponding substrate, which is suitable for substrates with flat surfaces and no protruding structures.

[0014] Another aspect of this application provides a hot press, which includes a frame, a heating device, and a drive device. The frame is configured with a heating device mounting area. The heating device includes the aforementioned heat transfer heater, which is mounted in the heating device mounting area. The free side of one of the substrates on one side is directly or indirectly fixedly connected to the first side of the heating device mounting area. The drive device is configured on the second side of the heating device mounting area and is used to control the movement of another substrate located on the side, thereby realizing the opening or closing of the hot pressing channel.

[0015] Furthermore, at least a portion of the substrate is made of a thermally conductive material, and the substrate made of a thermally conductive material is equipped with a heating element. The substrate equipped with the heating element forms a heated substrate, thereby releasing heat.

[0016] Furthermore, the edge pressing part is integrally formed with the corresponding substrate, and this structure facilitates the manufacturing of the edge pressing part and the substrate.

[0017] Furthermore, the substrate and the edge pressing part are constructed as arc-shaped structures, and the arc of the edge pressing part is the same as that of the corresponding substrate. The above arrangement ensures that the arc of the edge pressing part is consistent with that of the substrate, thereby adhering to the substrate.

[0018] Compared with the prior art, the heat transfer heater and hot press of this application, by configuring edge pressing parts at the edges of the two side substrates respectively, and the edge pressing parts and each substrate together form a hot pressing channel, thereby hot pressing the part of the substrate located between the edges of the two side substrates, improving the quality and area of ​​heat transfer, and solving the defect that the opening position of the existing flexible heater cannot be hot pressed to fully adhere to the substrate.

Detailed Implementation

[0020] See Figures 1 to 5 This application generally relates to a heat transfer heater 10 and a hot press using the heat transfer heater 10. The heat transfer heater 10 is used to perform heat transfer on cylindrical substrates such as cups. This embodiment provides two specific configurations of the heat transfer heater 10.

[0021] See Figures 1 to 5As a first configuration of the heat transfer heater 10: the heat transfer heater 10 includes two or more rigid substrates 1, each substrate 1 having an inner side with a pressing surface 110 extending between its two ends; the two or more rigid substrates 1 are movably coupled to each other on their adjacent sides; the free sides 104 of two substrates 1 located on the sides of the heat transfer heater 10 are arranged apart and not connected, each having a mounting connection portion 108 extending axially to the corresponding ends of the substrate 1; the inner wall of the mounting connection portion 108 extends along... An edge pressing portion 109 extends axially at least partially and is continuous with the inner side of the corresponding substrate 1. Two or more rigid substrates 1 and the edge pressing portion 109 enclose each other to form a hot pressing channel 100. The free side 104 of the substrate is configured to adjust the inner diameter of the hot pressing channel 100 by relative driving, thereby realizing the opening or closing of the hot pressing channel 100. That is to say, the inner diameter of the hot pressing channel 100 can be changed by driving the substrate 1 to move through the free side 104 of the substrate, thereby realizing the opening or closing of the hot pressing channel 100.

[0022] The heat transfer collector 10 with this configuration has the following two configurations for its edge pressing portion 109: I. For example Figure 1 As shown, the edge pressing portion 109 is arranged axially on a portion of the inner wall of the mounting connection portion 108. This arrangement allows a clearance space 109' to be formed between the inner walls of the mounting connection portions 108 on both sides, outside the edge pressing portion 109. This clearance space 109' is suitable for protruding protrusions on the surface of the substrate s, especially for heat transfer printing on cups with handles, for example... Figure 10 The image shows a heat transfer printing process used for mugs.

[0023] 2. The edge pressing portion 109 extends axially to both ends of the mounting connection portion 108. This configuration, where the edge pressing portion 109 axially covers the inner wall of the mounting connection portion 108, is particularly suitable for heat transfer printing on substrates with flat surfaces and no protruding structures, such as... Figure 9 The image shows a heat transfer printing method used for cylindrical cups.

[0024] The inner walls of the mounting connection 108 on the free sides 104 of the two substrates are constructed as relatively parallel planes, which can avoid interference between the two mounting connection 108s.

[0025] See Figures 1 to 5As a second arrangement of the heat transfer heater 10 (the difference between this arrangement and the first arrangement is that this arrangement does not have a mounting connection part 108, and its edge pressing part 109 extends directly from the edge of the base 1): The heat transfer heater 10 includes two or more rigid bases 1, and each base 1 has a pressing surface 110 extending between its two ends on its inner side. The two or more rigid bases 1 are movably coupled to each other on their adjacent sides. The two bases 1 located on the sides are arranged apart and not connected. The free side 104 of the base is at least partially constructed with an edge pressing part 109 along the axial direction. The edge pressing part 109 extends out of the inner wall of the corresponding base 1 and is continuous with the inner side of the base 1. The two or more rigid bases 1 and the edge pressing part 109 enclose each other to form a hot pressing channel 100. The free side 104 of the base is configured to allow the inner diameter of the hot pressing channel 100 to be adjusted by relative driving. This allows the hot pressing channel 100 to be opened or closed. In other words, the inner diameter of the hot pressing channel 100 can be changed by driving the movement of the substrate 1 through the free side 104 of the substrate, thereby opening or closing the hot pressing channel 100.

[0026] In this type of heat transfer collector 10, the edge pressing portion 109 is provided in the following two ways: 1. The edge pressing portion 109 is arranged axially on a portion of the inner wall of the corresponding substrate 1. This arrangement enables a clearance space 109' to be formed between the inner walls of the substrate 1 on both sides, in the area outside the edge pressing portion 109. The clearance space 109' can be used for protruding structures on the surface of the substrate s, such as for heat transfer printing on cups with handles.

[0027] 2. The edge pressing portion 109 extends axially to both ends of the corresponding substrate 1. The edge pressing portion 109 of this arrangement covers the inner wall of the corresponding substrate 1 axially, which is suitable for substrates s with flat surfaces and no protruding structures.

[0028] In the two configurations of the heat transfer heater 10 described above, the continuity between the edge pressing portion 109 and the inner side of the corresponding substrate 1 means that the pressing surface 110 of the substrate 1 is smoothly connected to the inner surface of the edge pressing portion 109. Specifically, as shown in the example... Figure 7 As shown, the substrate 1 and the edge pressing part 109 are constructed in an arc shape, and the edge pressing part 109 has the same curvature as the corresponding substrate 1. The above arrangement ensures that the edge pressing part 109 and the substrate 1 have the same curvature, thereby adhering to the substrate s.

[0029] In order to improve the integrity of the substrate 1 and facilitate the manufacturing of the edge pressing part 109 and the substrate 1, the edge pressing part 109 and the corresponding substrate 1 are integrally formed.

[0030] See Figures 1 to 6 , Figures 8 to 10The working principle of the heat transfer heater 10 of this application is as follows: During operation, the transfer material is wrapped on the surface of the substrate s, and the flexible heat-conducting layer 2 is wrapped on the outside of the substrate s containing the transfer material to obtain a transfer assembly s'. The transfer assembly s' is loaded into the hot pressing channel 100. By driving the free side 104 of the corresponding substrate 1 to adjust the inner diameter of the hot pressing channel 100 to decrease, the pressing surfaces 110 of each substrate 1 are pressed tightly against the transfer material and the substrate s through the flexible heat-conducting layer 2. The substrate 1 generates heat and transfers it to the transfer material and the substrate s through the flexible heat-conducting layer 2. After maintaining the pressing state for a preset time (the time is specifically set according to the material of the transfer material and the power of the heater 10), the hot pressing channel 100 is opened, the transfer assembly s' is taken out, and the heat transfer is completed.

[0031] The flexible thermally conductive layer 2 involved in this application uses a flexible material with good thermal conductivity, such as high-temperature thermally conductive silicone. In one specific embodiment, the thermal conductivity of the flexible thermally conductive layer is ≥1. In one specific embodiment, the flexible thermally conductive layer comprises 50-70% thermally conductive material, 20-30% methyl vinyl silicone rubber, 10-20% precipitated silica (precipitated silicon dioxide), 1-3% hydroxyl silicone oil, and 0.1-0.5% internal mold release agent. The thermally conductive material is composed of 60-80% silicone rubber, 20-30% thermally conductive filler, and additives (not more than 5%). The thermally conductive filler can be alumina, boron nitride, graphene, etc., and the additives are flame retardants, anti-aging agents, crosslinking agents, etc. The internal mold release agent is added to the interior of the above polymer material system to reduce the adhesion between the product and the mold, thereby reducing the application of external mold release agent and improving the demolding efficiency. Its main component is an organosilicon polymer, which can form a smooth protective film on the surface of the silicone mold.

[0032] The flexible thermally conductive layer 2 is configured to cover the substrate s containing the transfer material and is separably and fits against the pressing surfaces 110 of each substrate 1 in the hot pressing channel 100. The flexible thermally conductive layer 2 is used to transfer the heat and pressure of the heater 10 to the transfer material and the substrate s. The flexible thermally conductive layer 2 has a deployable structure, and when it is rolled up to the outer surface of the transfer material, its two ends come close together, forming an internal space for accommodating the substrate s. The two ends of the flexible thermally conductive layer 2 constitute its joint edges. In some embodiments, the joint edges of the flexible thermally conductive layer 2 are provided with a clearance area, that is, the distance between the two ends of the flexible thermally conductive layer 2 constitutes the clearance area. This clearance area is used to avoid protruding structures of the substrate s, such as the handle or the connection part of the handle on the cup.

[0033] As a specific implementation method, such as Figures 1 to 5As shown, each substrate 1 is made of thermally conductive material and equipped with a heating element 12. The substrate 1 releases heat through the heating element 12. Specifically, the heating element 12 is arranged in a ring along the edge of the corresponding substrate 1. Of course, in some embodiments, some substrates 1 can be made of thermally conductive material, and heating elements 12 can be arranged on these substrates 1 made of thermally conductive material, while other substrates can be made of non-thermally conductive material and do not need to be equipped with heating elements 12. These substrates 1 made of non-thermally conductive material are responsible for transmitting pressure, while the substrates 1 made of thermally conductive material are responsible for transmitting both heat and pressure. Of course, substrates 1 that do not need to be equipped with heating elements 12 can also be made of thermally conductive material, depending on actual needs. For example, in some cases, since the position and area of ​​the pattern to be transferred on the substrate s are concentrated on some substrates 1, some substrates 1 do not need to be heated, that is, they do not need to be equipped with heating elements 12. In this case, the part of substrate 1 without heating elements 12 can be made of non-thermally conductive material, or it can be uniformly made of thermally conductive material. For the substrate 1 that needs to be heated, a corresponding heating element 12 is configured.

[0034] The difference between the thermally conductive material and the non-thermally conductive material referred to in the rigid matrix 1 of this application lies in the strength of their thermal conductivity, which can be quantified by the thermal conductivity (λ): Thermally conductive materials: such as the following metal or non-metal materials with thermal conductivity ≥1 W / (m·K), such as metals (e.g., copper λ≈401, aluminum λ≈237), high thermal conductivity non-metals (e.g., graphene λ≈1000–5000, aluminum nitride ceramics λ≈170–280, silicon carbide λ≈120–200), etc. Non-thermal conductive materials: such as non-metallic materials with thermal conductivity <0.12 W / (m·K), such as rock wool board (λ<0.04), polyurethane foam (λ≈0.02–0.03), vacuum insulation board (λ≈0.004), etc.

[0035] That is, thermally conductive materials (λ≥1) accelerate heat transfer to dissipate heat, while non-thermally conductive materials (λ<0.12) impede heat transfer to provide insulation.

[0036] The substrate 1 of this application can be made of materials with good thermal conductivity, such as aluminum or its alloys, copper or its alloys, or other metallic materials such as stainless steel or its alloys, cast iron, or other known metallic or non-metallic materials with good thermal conductivity. The substrate 1 can be manufactured using die casting or other existing known processes. In some embodiments, the heating element 12 is a tubular heating element, which is laid on the surface of the corresponding substrate 1 to form a heating substrate. Specifically, it can be integrated with the substrate 1 using a die casting process. The heating substrate formed by this method has good thermal conductivity and better structural stability.

[0037] The substrate 1 of this invention is made of rigid thermally conductive material. Each substrate 1 is dynamically coupled. Due to the rigidity of the substrate 1, it has good structure and stability, long lifespan, and high reliability, ensuring uniform force applied to the transfer material and the substrate s. Furthermore, the design separating the substrate 1 from the flexible thermally conductive layer 2 allows for the installation of flexible thermally conductive layers 2 with corresponding sizes, thicknesses, and moduli during heat transfer, according to the specifications and requirements of different substrates s. This not only provides strong versatility but also facilitates the production, maintenance, and replacement of the heater 10 and the flexible thermally conductive layer 2. In addition, after the operation is completed, the flexible thermally conductive layer 2, along with the substrate s and the transfer material, detaches from the hot-pressing channel 100, thus separating from the substrate 1. This avoids the flexible thermally conductive layer 2 being heated by the substrate 1 after the operation is completed, effectively solving the problem of odor generated by prolonged heating of the flexible substrate due to the integrated structure of the flexible substrate and the flexible heating layer in existing flexible heaters.

[0038] See Figures 1 to 5 As a specific implementation of the movable coupling between substrates 1, two adjacent substrates 1 are connected by one or more hinge structures 1.4, such as... Figures 3 to 5 As shown, in this embodiment, three hinge structures 1.4 are provided along the axial direction of the base 1. The one or more hinge structures 1.4 include a hinge shaft 1.42 disposed on the side of one of two adjacent heating bases 1, and a hinge seat 1.41 disposed on the side of the other adjacent to the hinge shaft 1.42. The hinge seat 1.41 is constructed with a concave engagement portion 1.410, which rotatably engages with the hinge shaft 1.42 by inserting into the hinge channel 1.40.

[0039] like Figure 4 and Figure 5As shown, this embodiment also provides a specific implementation of a heat transfer heater 10. The heat transfer heater 10 is configured with three rigid substrates 1, specifically including a first side heating substrate 101, a second side heating substrate 102, and an adjacent heating substrate 103 disposed between the first side heating substrate 101 and the second side heating substrate 102. Each of the three rigid substrates 1 has a pressing surface 110 extending between its two ends. The first side heating substrate 101 and the second side heating substrate 102 are hinged together by an adjacent heating substrate 103. The first side heating substrate 101 and the second side heating substrate 102 are... Three hinge seats 1.41 are axially arranged on the sides of the two side heating bases 102 that are adjacent to the adjacent heating bases 103. The sides of the adjacent heating bases 103 that are adjacent to the first side heating base 101 and the second side heating base 102 are provided with hinge shafts 1.42 that are rotatably coupled to the corresponding hinge seats 1.41. The first side heating base 101 and the second side heating base 102 are respectively constructed with one side of their hinge seats 1.41 to form the aforementioned base free side 104. By driving the base free side 104, the concave joint portion 1.410 can rotate around the corresponding hinge shaft 1.42. The axial direction of this utility model is... Figure 4 The x-direction.

[0040] This invention employs multiple separate rigid substrates 1, which are rotatably connected and enclosed to form a heat-pressing channel 100 using a hinge structure 1.4. The rotatable and adjustable heat-pressing channel 100 avoids the material fatigue failure problem caused by repeated bending of the thin-walled metal shell of traditional flexible heaters, significantly improving the service life and reliability of the heater. The rigid heating substrate 1 ensures a tight fit between the heater and the substrate / transfer material, thereby improving the quality of heat transfer. Furthermore, the engagement method between the concave joint 1.410 and the hinge shaft 1.42 facilitates assembly and disassembly. During connection, simply insert the concave joint 1.410 into the hinge channel 1.40, and then align its opening with the hinge shaft 1.42 for engagement. This open coupling method offers greater freedom and a wider adjustable angle range, not only adapting to more substrate specifications but also facilitating adjustment and disassembly during operation.

[0041] See Figures 11 to 14Another aspect of this application provides a hot press, which includes a frame 3, a heating device 1', and a drive device 5. The heating device 1' includes a heat transfer heater 10 arranged in the first manner described above. The frame 3 is configured with a heating device mounting area 300. The heat transfer heater 10 is mounted in the heating device mounting area 300. The mounting connection part 108 of one of the bases 1 located on the side of the heat transfer heater 10 is directly or indirectly fixedly connected to the first side of the heating device mounting area 300. The drive device 5 is arranged on the second side of the heating device mounting area 300 and is used to control the movement of the other base 1 located on the side, thereby controlling the opening or closing of the hot press channel 100.

[0042] like Figure 1 , Figure 7 , Figure 13 and Figure 14 As shown, in this embodiment using three rigid substrates, the free side 104 of the heat transfer heater 10 is defined by the free side 104 of the first side heating substrate 101 and the second side heating substrate 102, specifically including... Figure 1 The first free side 106 of the first side heating substrate 101 and the second free side 107 of the second side heating substrate 102 are shown. The mounting connection portion 108 includes a first mounting connection portion 106' constructed on the first free side 106 and a second mounting connection portion 107' constructed on the second free side 107. The first connection portion 106' and the second mounting connection portion 107' are respectively connected to a first guide rail s1. The first side and the second side of the heating device mounting area 300 are respectively provided with a second guide rail s2. The first guide rail s1 and the second guide rail s2 are slidably engaged. This arrangement facilitates the engagement and disassembly of the heat transfer heater 10 and the frame 3. The driving device 5 acts on the second side heating base 102, driving the two first side heating bases 101 and the second side heating base 102 to move relative to each other, thereby adjusting the inner diameter of the hot pressing channel 100 and realizing the opening or closing of the hot pressing channel 100.

[0043] The hot press provided in another aspect of this application (not shown in the figures of this embodiment) includes a frame, a heating device, and a drive device. The frame is provided with a heating device mounting area. The heating device includes a heat transfer heater of a second configuration. The heat transfer heater is mounted in the heating device mounting area. The free side of one of the substrates on one side is directly or fixedly connected to the first side of the heating device mounting area. The drive device is disposed on the second side of the heating device mounting area and is used to control the movement of another substrate 1 located on the side, thereby controlling the opening or closing of the hot press channel 100.

[0044] Compared with the prior art, the heat transfer heater 10 and hot press of this application, by configuring edge pressing portions 109 at the edges of the two side substrates 1 respectively, and the edge pressing portions 109 together with each substrate 1 to form a hot pressing channel 100, can heat press the portion of the substrate s located between the edges of the two side substrates 1, thereby improving the quality and area of ​​heat transfer and solving the defect that the opening position of the existing flexible heater cannot heat press the substrate s. It should be noted that the protrusion size of the edge pressing portion 109 shown in the figure of this embodiment is small, but in actual application, the protrusion size of the edge pressing portion 109 can be set according to actual needs. For example, when the edge pressing portions 109 on both sides are set to protrude to the closed hot pressing channel 100, the edges of the edge pressing portions 109 on both sides are joined together, thereby performing 360-degree heat transfer on the substrate s.

[0045] like Figure 13 and Figure 14 As shown, the hot press also includes one or more swinging components 4, which are disposed on the second side of the heating device mounting area 300. One end of the swinging component 4 is oscillatingly connected to the lower side of the heating device mounting area 300 around the third swing axis R3, and the other end is directly or indirectly fixed to the free side 104 of the substrate corresponding to the heat transfer heater 10. Figure 13 As shown, one or more swing members 4 can be configured in a concave shape on the side adjacent to the heating device 1', similar to the shape trend of the outer surface of the heating device 1', so as to make the product structure more compact; in some embodiments, a transmission member 5.3 is also included, which is coupled to the swing member 4. The transmission member 5.3 can be controlled by the driving device 5 to drive the swing member 4 to swing, so as to adjust the size of the hot pressure channel 100 to realize the pressing and opening of the heater 10.

[0046] See Figures 10 to 14The drive unit 5 also includes a drive base 5.1 and an electric actuator 5.2. The drive base 5.1 is oscillatingly connected to the frame 3 around a first swing axis R1. The electric actuator 5.2 is fixedly mounted on the drive base 5.1. The first end of the transmission member 5.3 is oscillatingly connected to the swing member 4 around a second swing axis R2, and its second end is directly or indirectly coupled to the electric actuator 5.2. While the electric actuator 5.2 drives the transmission member 5.3 to move linearly relative to the drive base 5.1, it also drives the drive base 5.1 and the transmission member 5.3 to oscillate adaptively around the first swing axis R1 and the second swing axis R2, thereby driving the second mounting connection 107' to move relative to the first connection 106', realizing the pressing and opening of the heater 10. The electric actuator 5.2 and the transmission member 5.3 can be coupled through a screw and nut mechanism, or the electric actuator 5.2 can be directly set as a cylinder, using the cylinder's telescopic rod to directly couple with the transmission member 5.3. Alternatively, the electric actuator 5.2 can be configured as a motor to drive the transmission member 5.3 through a gear system and a connecting mechanism.

[0047] See Figures 11 to 14 The heating device 1' also includes a heat insulation shell 1.5, which covers the heat transfer heater 10 and is equipped with a first coupler e1 that is electrically connected to the heat transfer heater 10.

[0048] The heat insulation outer shell 1.5 may include two or more heat insulation sub-shells 1.50 formed by hinges via a connecting part 1.53, such as Figure 10 As shown, the heat insulation shell 1.5 includes a first sub-shell 1.51 and a second sub-shell 1.52, which are hinged together by a connecting portion 1.53. At least one connecting portion 1.53 corresponds to the opening side of the hot-pressing channel 100, that is, to the free side 104 of the two substrates 1 that are spaced apart and not connected. The fact that at least one connecting portion 1.53 corresponds to the opening side of the hot-pressing channel 100 allows the heat insulation shell 1.5 to correspond to the changing trend and position of the heater 10 as the hot-pressing channel 100 opens and closes, thus avoiding interference with the opening and closing of the hot-pressing channel 100.

[0049] See Figure 12 , Figure 13 ,and Figure 14 The heat-insulating housing 1.5 is constructed with a first coupler mounting base e1'. The first coupler e1 is mounted to the first coupler mounting base e1' in the direction of the heat transfer heater 10 loading heating device mounting area 300. The frame 3 is constructed with a second coupler e2 electrically connected to the circuit of the hot press on the side of the heating device mounting area 300. The second coupler e2 is mounted on the frame 3 with the first coupler e1 facing each other.

[0050] The couplers in this application, namely the first coupler e1 and the second coupler e2, are pluggable structures, typically including a male terminal and a female terminal. Both the male and female terminals include corresponding electrical terminals. The number of electrical terminals can be selected according to actual needs, such as the number of lines, specifically the number of power supply lines and detection lines. Figures 1 to 7 In the embodiment shown, when three power supply lines with three detection lines are used, six pairs of electrical terminals are configured.
