Description

Technical Field

[0001] The utility model relates to the technical field of heating plates, in particular to an epoxy resin heating plate with a stable structure. Background Art

[0002] A heating plate is a safe and reliable electric heating plate that generates heat when powered on, without any electrical charge or open flame. It is round or square in shape. Because it relies primarily on heat conduction, it has high thermal efficiency. An epoxy resin heating plate is a heating plate typically made of epoxy resin, offering high-temperature and corrosion resistance. It is widely used in applications such as lithium battery heating, 3D printers, and electronic equipment heating.

[0003] Most epoxy resin heating panels are relatively simple. The epoxy resin heating panel and the aluminum panel are separate and independent, and are assembled by double-sided tape. However, when used under high temperature for a long time, there is a probability that the heating panel and the aluminum panel will separate. Alternatively, the epoxy resin heating panel and the aluminum panel are assembled by screwing, which is more cumbersome and increases the screw material, material, processing and manufacturing costs. Therefore, the present application provides a structurally stable epoxy resin heating panel to meet the needs. Utility Model Content

[0030] First, the alloy heating wire 1 is pressed onto the lower semi-cured sheet 2 at high temperature, and then its circuit is formed by laser cutting technology or exposure and development. A layer of upper semi-cured sheet 3 is laid flat on the surface of the alloy heating wire 1, and then hot pressing and curing treatment is carried out by a hot press to ensure that the alloy heating wire 1, the lower semi-cured sheet 2 and the upper semi-cured sheet 3 are firmly bonded. Then, the required shape of the epoxy resin heating plate is opened on the shaping ring 7 through precision engraving technology to connect the positive and negative poles. The aluminum plate 6 is processed by a CNC machining center, and the surfaces of the processed aluminum plate 6 and the lower semi-cured sheet 2 are cleaned. The surface of the lower semi-cured sheet 2 is evenly coated with silicone coating 4, and the surface of the aluminum plate 6 is evenly coated with adhesion promoter 5. After air drying, the silicone coating 4 is laid flat on the adhesion promoter 5 for bonding, and then exhaust treatment is carried out to ensure that there are no bubbles remaining between the lower semi-cured sheet 2 and the silicone coating 4. In order to avoid affecting the thermal conductivity of the epoxy resin heating plate, the semi-finished product with good exhaust is placed flat on the working platform of the high-temperature vulcanizing machine equipment. After vulcanization, the semi-finished product is taken out and cooled naturally. The semi-finished epoxy resin heating plate is connected to the positive and negative poles of the semi-finished epoxy resin heating plate with wires to obtain a heating plate assembly. The alloy heating wire 1, the lower semi-cured sheet 2 and the upper semi-cured sheet 3 constitute the epoxy resin heating plate. The aluminum plate 6 is vulcanized as a whole to form a heating plate assembly to avoid loosening or falling off caused by bonding and fixing. In addition, the pi film in the cross-sectional structural layer is eliminated. The pi film is used as a carrier to facilitate circuit exposure and development, and the heating circuit is etched out, so that the epoxy resin heating plate can be formed in one go. The alloy heating wire 1 can be formed by laser cutting technology, so that the epoxy resin heating plate can be formed in one go. The air between the silicone coating 4 and the lower semi-cured sheet 2 is exhausted by a roller exhaust machine, and then placed in the high-temperature vulcanizing equipment for vulcanization and molding.

[0031] like Figure 1 and Figure 2 As shown, the connecting mechanism 9 includes an energized connector 91 fixedly connected to the end of the alloy heating wire 1, and the shaping ring 7 is provided with a locking portion for locking the energized connector 91. The locking portion locks and fixes the energized connector 91 to prevent the energized connector 91 from bending and being damaged.

[0032] like Figure 3-5 As shown, a power connection part 98 is fixedly installed on one side of the power connection part 91, and one end of the conductive wire 8 is rotatably connected to a wire end connection part 99. The inner wall of the wire end connection part 99 is threadedly connected to the outer wall of the power connection part 98, so that the conductive wire 8 can be easily disassembled and installed on one side of the alloy heating wire 1.

[0033] like Figure 3 As shown, an insulating connector 92 is fixedly mounted on the outer wall of the power connector 91 . The insulating connector 92 is clamped on one side of the clamping portion of the fixed ring 7 . The insulating connector 92 limits the position of the power connector 91 .

The raised ring 95 is arranged inside the movable groove 93, and the wire end connector 99 is arranged inside the connecting sleeve 94, pushing the connecting sleeve 94 to slide on the outer wall of the insulating connector 92, and the raised ring 95 slides on the outside of the movable groove 93. When the wire end connector 99 is connected to one side of the power connection part 98, it is inside the connecting sleeve 94. The connecting sleeve 94 protects the power connection part 98 and the wire end connector 99 to prevent the power connection part 98 and the wire end connector 99 from being damaged by pressure deformation.

[0035] like Figure 3-5 As shown, one side of the raised ring 95 is rotatably connected to a connecting ring 96, and one side of the connecting ring 96 is fixedly installed with a spring 97. The spring 97 is arranged inside the movable groove 93, and the other end of the spring 97 is fixedly connected to the outer wall of the insulating connector 92. When the power connection part 98 and the line end connector 99 are connected, the connecting sleeve 94 slides on the outer wall of the insulating connector 92, and the connecting ring 96 drives the spring 97 to gradually stretch.

[0036] like Figure 3-5 As shown, the outer wall of the wire end connector 99 is fixedly installed with multiple limiting protrusions 910, and the outer wall of the connecting sleeve 94 is provided with multiple limiting grooves 911 that cooperate with the limiting protrusions 910.

The wire end connector 99 and the limiting protrusions 910 are rotated to drive the connecting sleeve 94 and the raised ring 95 to rotate outside the insulating connector 92. The raised ring 95 and the connecting ring 96 rotate relative to each other, gradually connecting the power connection 98 and the wire end connector 99 together to realize the installation of the alloy heating wire 1 and the conductive wire 8.

[0037] like Figure 5 As shown, the edge of the limiting groove 911 is provided with a rounded chamfer to facilitate the limiting protrusion 910 to be snapped into the limiting groove 911 .

[0038] The technical solution provided by the utility model is to first press the alloy heating wire 1 on the lower semi-preg sheet 2 at high temperature, and then form the alloy heating wire 1 by laser cutting technology or exposure and development. A layer of upper semi-preg sheet 3 is laid flat on the surface of the alloy heating wire 1, and then hot pressing and curing treatment is carried out by a hot press to make the alloy heating wire 1, the lower semi-preg sheet 2 and the upper semi-preg sheet 3 firmly bonded. Then, the required shape of the epoxy resin heating plate is formed on the shaping ring 7 by precision engraving technology, and the positive and negative electrodes are connected. The aluminum plate 6 is processed by a CNC machining center. , clean the surfaces of the processed aluminum plate 6 and the lower prepreg 2, evenly apply the silicone coating 4 on the surface of the lower prepreg 2, and evenly apply the adhesion promoter 5 on the surface of the aluminum plate 6. After the air drying time, spread the silicone coating 4 on the adhesion promoter 5 for bonding, and then perform exhaust treatment to ensure that there are no bubbles left between the lower prepreg 2 and the silicone coating 4. Place the semi-finished product with exhaust flat on the work platform of the high-temperature vulcanizer equipment. After vulcanization, take out the semi-finished product and cool it naturally. Connect the positive and negative poles of the epoxy resin heating plate of the semi-finished product to the wires to obtain the heating plate assembly;

[0039] The wire end connector 99 is inserted into the interior of the connecting sleeve 94, and the limiting protrusion 910 is clamped in the interior of the limiting groove 911. The wire end connector 99 and the limiting protrusion 910 are rotated to drive the connecting sleeve 94 and the protruding ring 95 to rotate outside the insulating connector 92. The protruding ring 95 and the connecting ring 96 rotate relative to each other. The connecting sleeve 94 slides on the outer wall of the insulating connector 92, and the protruding ring 95 slides on the outside of the movable groove 93. The connecting ring 96 drives the spring 97 to gradually stretch. When the wire end connector 99 is connected to one side of the power connection part 98, it is inside the connecting sleeve 94, and the power connection part 98 is gradually connected to the wire end connector 99, thereby realizing the installation of the alloy heating wire 1 and the conductive wire 8.
