[0037] Hot pressing technology is a molding process that uses heat and pressure to tightly bond or densify materials in a mold, and it is widely used in modern industrial manufacturing. However, traditional hot pressing production lines lack real-time pressure data monitoring and recording, thus failing to adjust the pressure in real time, reducing adjustability and reliability. Secondly, traditional hot pressing processes use constant-temperature heating plates, resulting in large temperature fluctuations and uneven activation of the hot-pressed adhesive. Thirdly, when the mechanical pressure head directly and rigidly contacts brittle glass, local pressure deviations can easily cause micro-cracks.

Figure 2 for Figure 1 A partial structural schematic diagram of the hot pressing device 100. (See attached diagram.) Figure 1 As shown, this utility model proposes a hot pressing device 100 and processing equipment. The hot pressing device 100 of this utility model includes a support frame 10, a moving component 20, a pressure sensor 30, a hot pressing component 40, and a cooling fan 50.

When multiple hot pressing heads 43 are used, it is also possible to operate on more complex structures of parts to be hot pressed, improving versatility.
[0045] By using the hot pressing device 100 in this technical solution, the support frame 10 is used to support and fix the moving component 20, the pressure sensor 30 and the hot pressing component 40.

The heat insulation plate 44 encloses a heat-insulating space, and a portion of the heating element 42 is located within this space. In this embodiment, the heat insulation plate 44 is connected to the connecting member 41 and the hot pressing head 43, and encloses a portion of the heating element 42 and a portion of the thermocouple 45. This prevents the heat from the heating element 42 from dissipating outwards, thereby preventing damage to other equipment components or personnel and improving safety performance.
[0049] Specifically, in this embodiment, the heat insulation plate 44 and the connector 41 are detachably connected, which can improve the efficiency of disassembly and assembly between the heat insulation plate 44 and the connector 41.
[0050] Specifically, in this embodiment, the side of the heat insulation plate 44 away from the connector 41 is connected to the connecting part 432.

The connector 41 is covered by the first opening and the connecting part 432 is covered by the second opening, which can further prevent the heat of the heating element 42 from spreading outward and further improve the safety performance.
[0051] Specifically, in this embodiment, the heating rod is located in the heat insulation space, and the heat insulation plate 44 can prevent heat from spreading outward, thereby improving safety performance.
[0052] In some embodiments of this utility model, such as Figure 2 and 3 As shown, the heat insulation plate 44 includes a first heat insulation part 441, a second heat insulation part 442, a third heat insulation part and a fourth heat insulation part 443 connected in sequence. The first heat insulation part 441, the second heat insulation part 442, the third heat insulation part and the fourth heat insulation part 443 enclose a heat insulation space. The fourth heat insulation part 443 has a first opening, and another part of the heating element 42 extends to the outside through the first opening. In this embodiment, the first heat insulation part 441 and the third heat insulation part are respectively arranged perpendicularly to the second heat insulation part 442, and the first heat insulation part 441 and the third heat insulation part are respectively arranged perpendicularly to the fourth heat insulation part 443. The first heat insulation part 441 and the third heat insulation part are arranged in parallel, and the second heat insulation part 442 and the fourth heat insulation part 443 are arranged in parallel. The top ends of the first heat insulation part 441, the second heat insulation part 442, the third heat insulation part, and the fourth heat insulation part 443 are respectively connected to the connector 41. The bottom ends of the first heat insulation part 441, the second heat insulation part 442, the third heat insulation part, and the fourth heat insulation part 443 are respectively connected to the connecting part 432.
[0053] Specifically, in this embodiment, the heating element 42 further includes a connecting wire 421 electrically connected to the heating rod. The connecting wire 421 can extend to the outside through the first opening and then be connected to an external power supply and / or regulator, and can adjust the temperature of the heating element 42 in real time according to the data of the thermocouple 45 or the specific operating conditions.
[0054] Specifically, in this embodiment, the fourth heat insulation part 443 has a second opening, through which the connecting wire of the thermocouple 45 can extend to the outside of the heat insulation plate 44.
[0055] In some embodiments of this utility model, such as Figure 2 and 3As shown, the hot pressing device 100 also includes an elastic element 60, which is disposed between the pressure sensor 30 and the hot pressing assembly 40. The elastic element 60 is a spring. In this embodiment, after the hot pressing assembly 40 contacts the workpiece to be hot-pressed, it transmits force to the pressure sensor 30 through the elastic element 60, thereby realizing thermal pressure feedback. The elastic element 60 can buffer the pressure of the pressure sensor 30, thus preventing the pressure sensor 30 from being damaged due to a large reaction force.
[0056] On the other hand, when the hot pressing assembly 40 comes into contact with the workpiece to be hot pressed, the drive member 21 can adjust the elastic force of the elastic member 60 by moving, thereby achieving the hot pressure on the workpiece to be hot pressed.
[0057] In some embodiments of this utility model, such as Figure 1 As shown, two cooling fans 50 are provided, and the two cooling fans 50 are arranged opposite each other on both sides of the drive component 21. In this embodiment, the two cooling fans 50 can better dissipate heat from the drive component 21, thereby improving the heat dissipation capacity.
[0058] Specifically, in this embodiment, the cooling fan 50 and the support frame 10 are detachably connected. The detachable connection facilitates the disassembly and assembly of the cooling fan 50, thereby improving the efficiency of disassembly and assembly.
[0059] In some embodiments of this utility model, the driving component 21 is an electric cylinder. In this embodiment, the electric cylinder (electric cylinder), as a core driving component in modern industrial automation, is gradually replacing traditional pneumatic and hydraulic cylinders due to its significant advantages such as high-precision control, energy saving and environmental protection, easy maintenance, and strong environmental adaptability. Its core advantages can be summarized into three dimensions: precise motion control, optimized energy efficiency, and intelligent system integration, meeting diverse needs from precision manufacturing to complex industrial scenarios. The electric cylinder can drive the moving component 22 towards the component to be heated. Combined with the pressure sensor 30, it can detect thermal pressure in real time and adjust accordingly, improving reliability.
[0060] Furthermore, the hot pressing device 100 of this invention employs a floating structure of elastic element 60 and hot pressing head 43, and uses the combined control of electric cylinder and pressure sensor 30 to provide real-time feedback of hot pressing pressure (accuracy ±0.2N), solving the over-pressure / under-pressure problem caused by the thickness tolerance of the parts to be hot-pressed in the prior art. The hot pressing device 100 can also record temperature-pressure-time curves, enabling the establishment of a correlation model between process parameters and bonding strength.
[0061] Heat is transferred to the hot press head 43 via a built-in heating rod, ensuring that the temperature of the workpiece reaches the activation temperature of the hot press adhesive, thus achieving the hot press adhesion function between the hot press adhesive and the workpiece. Temperature feedback and adjustment are achieved via thermocouple 45, and the electric cylinder moves the hot press assembly 40 to the pressure holding position to perform hot press adhesive on the workpiece, achieving precise control between the hot press head 43 and the workpiece. The pressure sensor 30 provides feedback to the electric cylinder to automatically adjust the spring compression, ensuring the press head reaches the holding pressure, thus achieving pressure monitoring and feedback during the hot press process, and real-time adjustment.
[0062] Furthermore, the operation process of the hot pressing device 100 of this utility model is as follows: the electric cylinder presses down, driving the hot pressing assembly 40 to descend to the preheating pressure position of the workpiece to be pressed; the electric cylinder continues to press down, the pressure output spring is compressed, the pressure sensor 30 is subjected to force, and the pressure is fed back in real time during the pressing process until the pressure set value is reached; after the hot pressing time is reached, the pressure head is lifted, the electric cylinder is lifted, and the hot pressing is completed.
[0063] This utility model also proposes a processing equipment having the above-mentioned hot pressing device 100.
[0064] By using the hot pressing device 100 of the processing equipment in this technical solution, the support frame 10 is used to support and fix the moving component 20, the pressure sensor 30, the hot pressing component 40 and the cooling fan 50. The moving component 22 can be moved by the driving component 21, and drive the pressure sensor 30 and the hot pressing component 40 to move toward the workpiece to be hot pressed, thereby realizing the hot pressing operation. The pressure sensor 30 can provide real-time feedback on the pressure of the hot pressing component 40 on the workpiece to be hot pressed, and thus adjust it in real time, improving reliability. In addition, the cooling fan 50 can dissipate heat from the driving component 21, improving the heat dissipation capacity.
